Subject [jira] [Commented] (HIVE-9292) CBO (Calcite Return Path): Inline GroupBy, Properties
Date Thu, 15 Jan 2015 23:41:34 GMT


Jesus Camacho Rodriguez commented on HIVE-9292:

Yes, I could get rid of the groupOpToInputTables object in ParseContext.
However, ParseContext is still used by RewriteQueryUsingAggregateIndexCtx, as it needs to
retrieve the RowResolver for the group operator that is retrieved from the tree. 
Once HIVE-9327 goes in, RewriteQueryUsingAggregateIndexCtx won't use any of the data structures
in ParseContext anymore.

I will wait till HIVE-9200 goes in to rebase the patch and upload it again.
