[meethngala]

Dear Gobblin maintainers,

Please accept this PR. I understand that it will not be reviewed until I have checked off all the steps below!

JIRA

• My PR addresses the following Gobblin JIRA issues and references them in the PR title. For example, "[GOBBLIN-XXX] My Gobblin PR"
  • https://issues.apache.org/jira/browse/GOBBLIN-1835

Description

I want to upgrade our iceberg version to 1.2.0 to leverage performance improvements such as optimized metadata caching, reduced memory consumption, and faster metadata commits, enhanced APIs, schema evolution. Most importantly it natively provides support for Apache Spark 3.x, allowing seamless integration and improved performance when using Iceberg with Spark. As part of this upgrade, below are the major changes:

• Update method signatures for CatalogUtil.loadCatalog() and Snapshots.allManifests
• Initialize and load HiveCatalog via CatalogUtil inside IcebergMetadataWriter

Tests

• My PR adds the following unit tests OR does not need testing for this extremely good reason:
• Updated unit tests
• Successful Build

Commits

• My commits all reference JIRA issues in their subject lines, and I have squashed multiple commits if they address the same issue. In addition, my commits follow the guidelines from "How to write a good git commit message":
  1. Subject is separated from body by a blank line
  2. Subject is limited to 50 characters
  3. Subject does not end with a period
  4. Subject uses the imperative mood ("add", not "adding")
  5. Body wraps at 72 characters
  6. Body explains "what" and "why", not "how"
