[SPARK-12689][SQL] Migrate DDL parsing to the newly absorbed parser by viirya · Pull Request #10723 · apache/spark

viirya · 2016-01-12T10:08:26Z

JIRA: https://issues.apache.org/jira/browse/SPARK-12689

DDLParser processes three commands: createTable, describeTable and refreshTable.
This patch migrates the three commands to newly absorbed parser.

@viirya can you rename the title to "migrate describe table parsing to ..."

viirya · 2016-01-13T05:07:42Z

Because SQLContext still uses DDLParser, looks like I can't simply remove describeTable command from DDLParser. So I can't gradually migrate these three commands in three PRs.

@cloud-fan Can you also take a look? It is related to the work of adding DDL support for creating bucketed tables.

Why change this? You didn't touch the describe stuff in SparkSqlParser.g right?

Yes. I think it is incorrect from beginning but not be tested it out because we don't reach here before. I've tested it locally. Once all three commands are migrated, we can see this passing tests.

if we parse the following SQL using the parse driver org.apache.spark.sql.catalyst.parser.ParseDriver.parsePlan("DESCRIBE EXTENDED tbl.a", null)

We would end up with the following AST:

TOK_DESCTABLE 1, 0, 6, 18 :- TOK_TABTYPE 1, 4, 6, 18 : +- TOK_TABNAME 1, 4, 6, 18 : :- tbl 1, 4, 4, 18 : +- a 1, 6, 6, 22 +- EXTENDED 1, 2, 2, 9

This change would pick this up, and old code didn't (I am sure I tested this though :S ). You can disable this in the DDL parser, to see if it works now.

Could we add a test for this? The Hive test suite apparently misses this one. I could also address in a different PR.

Actually we have test for describe table command in HiveQuerySuite. Do we need another test?

How about gradually moving functionality from the DLL parser to SparkQl? That would allow us to test this in the meantime.

~~DDLParser is still used in SQLContext. Do we want to completely remove it?~~ Because I already migrate three commands. I think we can test them all together.

Why not use unquoteString this does the same and is easier to read?

Don't know there is unquoteString. Thanks.

sql/catalyst/src/main/antlr3/org/apache/spark/sql/catalyst/parser/ExpressionParser.g

We are allowed to use From and To in CreateTableUsing command's options (actually seems we can use any string as the option key). But we can't simply add them into nonReserved because by doing that we mess other existing rules. So we create a looseIdentifier and looseNonReserved here.

Why not add this to the option rule directly?

Because I don't know if we will add other reserved words later. If so, the option rule might be too long. I don't count if any keywords are not included in nonReserved.

Both (current approach or adding it to the option rule) are okay for me.

Could add your initial line commentaar as a comment in the code?

Thanks for reminding. I've added it.

@viirya I have done another round.

Most things are minor, but I would to know why you want to change the treatment of quoted identifiers?

…Parser commands to new Parser This PR moves all the functionality provided by the SparkSQLParser/ExtendedHiveQlParser to the new Parser hierarchy (SparkQl/HiveQl). This also improves the current SET command parsing: the current implementation swallows ```set role ...``` and ```set autocommit ...``` commands, this PR respects these commands (and passes them on to Hive). This PR and #10723 end the use of Parser-Combinator parsers for SQL parsing. As a result we can also remove the ```AbstractSQLParser``` in Catalyst. The PR is marked WIP as long as it doesn't pass all tests. cc rxin viirya winningsix (this touches #10144) Author: Herman van Hovell <hvanhovell@questtec.nl> Closes #10905 from hvanhovell/SPARK-12866.

It is, can't make sense of this either. Are tests passing locally?

Yeah, I think so. And I don't update codes since last successful test.
