Jesus Camacho Rodriguez commented on HIVE-9200:
-----------------------------------------------

[~jpullokkaran], I attach a RB link, can you check it? I just want to know if we are on the same page.
In particular, I have inlined the QBJoinTree object; however, I kept _joinContext_, _mapJoinContext_, _smbMapJoinContext_ in the ParseContext as Sets, as there are optimizations in Hive that use these structures to iterate over e.g. all the map joins in a query. Should we definitively get rid of them in the ParseContext?
The second question concerns SemanticAnalyzer, as you said you do not want to change anything there. As I changed the data structures in ParseContext, I changed them accordingly in SemanticAnalyzer. Can you check it? Which do you think is the right way to approach this?
Thanks.
