* Added `assign-owner-group` command ([#3111](#3111)). The Databricks Labs Unity Catalog Exporter (UCX) tool now includes a new `assign-owner-group` command, allowing users to assign an owner group to the workspace. This group will be designated as the owner for all migrated tables and views, providing better control and organization of resources. The command can be executed in the context of a specific workspace or across multiple workspaces. The implementation includes new classes, methods, and attributes in various files, such as `cli.py`, `config.py`, and `groups.py`, enhancing ownership management functionality. The `assign-owner-group` command replaces the functionality of issue [#3075](#3075) and addresses issue [#2890](#2890), ensuring proper schema ownership and handling of crawled grants. Developers should be aware that running the `migrate-tables` workflow will result in assigning a new owner group for the Hive Metastore instance in the workspace installation. * Added `opencensus` to known list ([#3052](#3052)). In this release, we have added OpenCensus to the list of known libraries in our configuration file. OpenCensus is a popular set of tools for distributed tracing and monitoring, and its inclusion in our system will enhance support and integration for users who utilize this tool. This change does not affect existing functionality, but instead adds a new entry in the configuration file for OpenCensus. This enhancement will allow our library to better recognize and work with OpenCensus, enabling improved performance and functionality for our users. * Added default owner group selection to the installer ([#3370](#3370)). A new class, AccountGroupLookup, has been added to the AccountGroupLookup module to select the default owner group during the installer process, addressing previous issue [#3111](#3111). This class uses the workspace_client to determine the owner group, and a pick_owner_group method to prompt the user for a selection if necessary. The ownership selection process has been improved with the addition of a check in the installer's `_static_owner` method to determine if the current user is part of the default owner group. The GroupManager class has been updated to use the new AccountGroupLookup class and its methods, `pick_owner_group` and `validate_owner_group`. A new variable, `default_owner_group`, is introduced in the ConfigureGroups class to configure groups during installation based on user input. The installer now includes a unit test, "test_configure_with_default_owner_group", to demonstrate how it sets expected workspace configuration values when a default owner group is specified during installation. * Added handling for non UTF-8 encoded notebook error explicitly ([#3376](#3376)). A new enhancement has been implemented to address the issue of non-UTF-8 encoded notebooks failing to load by introducing explicit error handling for this case. A UnicodeDecodeError exception is now caught and logged as a warning, while the notebook is skipped and returned as None. This change is implemented in the load_dependency method in the loaders.py file, which is a part of the assessment workflow. Additionally, a new unit test has been added to verify the behavior of this change, and the assessment workflow has been updated accordingly. The new test function in test_loaders.py checks for different types of exceptions, specifically PermissionError and UnicodeDecodeError, ensuring that the system can handle notebooks with non-UTF-8 encoding gracefully. This enhancement resolves issue [#3374](#3374), thereby improving the overall robustness of the application. * Added migration progress documentation ([#3333](#3333)). In this release, we have updated the `migration-progress-experimental` workflow to track the migration progress of a subset of inventory tables related to workspace resources being migrated to Unity Catalog (UCX). The workflow updates the inventory tables and tracks the migration progress in the UCX catalog tables. To use this workflow, users must attach a UC metastore to the workspace, create a UCX catalog, and ensure that the assessment job has run successfully. The `Migration Progress` section in the documentation has been updated with a new markdown file that provides details about the migration progress, including a migration progress dashboard and an experimental migration progress workflow that generates historical records of inventory objects relevant to the migration progress. These records are stored in the UCX UC catalog, which contains a historical table with information about the object type, object ID, data, failures, owner, and UCX version. The migration process also tracks dangling Hive or workspace objects that are not referenced by business resources, and the progress is persisted in the UCX UC catalog, allowing for cross-workspace tracking of migration progress. * Added note about running assessment once ([#3398](#3398)). In this release, we have introduced an update to the UCX assessment workflow, which will now only be executed once and will not update existing results in repeated runs. To accommodate this change, we have updated the README file with a note clarifying that the assessment workflow is a one-time process. Additionally, we have provided instructions on how to update the inventory and findings by uninstalling and reinstalling the UCX. This will ensure that the inventory and findings for a workspace are up-to-date and accurate. We recommend that software engineers take note of this change and follow the updated instructions when using the UCX assessment workflow. * Allowing skipping TACLs migration during table migration ([#3384](#3384)). A new optional flag, "skip_tacl_migration", has been added to the configuration file, providing users with more flexibility during migration. This flag allows users to control whether or not to skip the Table Access Control Language (TACL) migration during table migrations. It can be set when creating catalogs and schemas, as well as when migrating tables or using the `migrate_grants` method in `application.py`. Additionally, the `install.py` file now includes a new variable, `skip_tacl_migration`, which can be set to `True` during the installation process to skip TACL migration. New test cases have been added to verify the functionality of skipping TACL migration during grants management and table migration. These changes enhance the flexibility of the system for users managing table migrations and TACL operations in their infrastructure, addressing issues [#3384](#3384) and [#3042](#3042). * Bump `databricks-sdk` and `databricks-labs-lsql` dependencies ([#3332](#3332)). In this update, the `databricks-sdk` and `databricks-labs-lsql` dependencies are upgraded to versions 0.38 and 0.14.0, respectively. The `databricks-sdk` update addresses conflicts, bug fixes, and introduces new API additions and changes, notably impacting methods like `create()`, `execute_message_query()`, and others in workspace-level services. While `databricks-labs-lsql` updates ensure compatibility, its changelog and specific commits are not provided. This pull request also includes ignore conditions for the `databricks-sdk` dependency to prevent future Dependabot requests. It is strongly advised to rigorously test these updates to avoid any compatibility issues or breaking changes with the existing codebase. This pull request mirrors another ([#3329](#3329)), resolving integration CI issues that prevented the original from merging. * Explain failures when cluster encounters Py4J error ([#3318](#3318)). In this release, we have made significant improvements to the error handling mechanism in our open-source library. Specifically, we have addressed issue [#3318](#3318), which involved handling failures when the cluster encounters Py4J errors in the `databricks/labs/ucx/hive_metastore/tables.py` file. We have added code to raise noisy failures instead of swallowing the error with a warning when a Py4J error occurs. The functions `_all_databases()` and `_list_tables()` have been updated to check if the error message contains "py4j.security.Py4JSecurityException", and if so, log an error message with instructions to update or reinstall UCX. If the error message does not contain "py4j.security.Py4JSecurityException", the functions log a warning message and return an empty list. These changes also resolve the linked issue [#3271](#3271). The functionality has been thoroughly tested and verified on the labs environment. These improvements provide more informative error messages and enhance the overall reliability of our library. * Rearranged job summary dashboard columns and make job_name clickable ([#3311](#3311)). In this update, the job summary dashboard columns have been improved and the need for the `30_3_job_details.sql` file, which contained a SQL query for selecting job details from the `inventory.jobs` table, has been eliminated. The dashboard columns have been rearranged, and the `job_name` column is now clickable, providing easy access to job details via the corresponding job ID. The changes include modifying the dashboard widget and adding new methods for making the `job_name` column clickable and linking it to the job ID. Additionally, the column titles have been updated to display more relevant information. These improvements have been manually tested and verified in a labs environment. * Refactor refreshing of migration-status information for tables, eliminate another redundant refresh ([#3270](#3270)). This pull request refactors the way table records are enriched with migration-status information during encoding for the history log in the `migration-progress-experimental` workflow. It ensures that the refresh of migration-status information is explicit and under the control of the workflow, addressing a previously expressed intent. A redundant refresh of migration-status information has been eliminated and additional unit test coverage has been added to the `migration-progress-experimental` workflow. The changes include modifying the existing workflow, adding new methods for refreshing table migration status without updating the history log, and splitting the crawl and update-history-log tasks into three steps. The `TableMigrationStatusRefresher` class has been introduced to obtain the migration status of a table, and new tests have been added to ensure correctness, making the `migration-progress-experimental` workflow more efficient and reliable. * Safe read files in more places ([#3394](#3394)). This release introduces significant improvements to file handling, addressing issue [#3386](#3386). A new function, `safe_read_text`, has been implemented for safe reading of files, catching and handling exceptions and returning None if reading fails. This function is utilized in the `is_a_notebook` function and replaces the existing `read_text` method in specific locations, enhancing error handling and robustness. The `databricks labs ucx lint-local-code` command and the `assessment` workflow have been updated accordingly. Additionally, new test files and methods have been added under the `tests/integration/source_code` directory to ensure comprehensive testing of file handling, including handling of unsupported file types, encoding checks, and ignorable files. * Track `DirectFsAccess` on `JobsProgressEncoder` ([#3375](#3375)). In this release, the open-source library has been updated with new features related to tracking Direct File System Access (DirectFsAccess) in the JobsProgressEncoder. This change includes the addition of a new `_direct_fs_accesses` method, which detects direct filesystem access by code used in a job and generates corresponding failure messages. The DirectFsAccessCrawler object is used to crawl and track file system access for directories and queries, providing more detailed tracking and encoding of job progress. Additionally, new methods `make_job` and `make_dashboard` have been added to create instances of Job and Dashboard, respectively, and new unit and integration tests have been added to ensure the proper functionality of the updated code. These changes improve the functionality of JobsProgressEncoder by providing more comprehensive job progress information, making the code more modular and maintainable for easier management of jobs and dashboards. This release resolves issue [#3059](#3059) and enhances the tracking and encoding of job progress in the system, ensuring more comprehensive and accurate reporting of job status and issues. * Track `UsedTables` on `TableProgressEncoder` ([#3373](#3373)). In this release, the tracking of `UsedTables` has been implemented on the `TableProgressEncoder` in the `tables_progress` function, addressing issue [#3061](#3061). The workflow `migration-progress-experimental` has been updated to incorporate this change. New objects, `self.used_tables_crawler_for_paths` and `self.used_tables_crawler_for_queries`, have been added as instances of a class responsible for crawling used tables. A `full_name` property has been introduced as a read-only attribute for a source code class, providing a more convenient way of accessing and manipulating the full name of the source code object. A new integration test for the `TableProgressEncoder` component has also been added, specifically testing table failure scenarios. The `TableProgressEncoder` class has been updated to track `UsedTables` using the `UsedTablesCrawler` class, and a new class, `UsedTable`, has been introduced to represent the catalog, schema, and table name of a table. Two new unit tests have been added to ensure the correct functionality of this feature.
