Russell Melick updated HIVE-1644:
---------------------------------
Attachment: HIVE-1644.5.patch
HIVE-1644.5.path
I have moved the processing into the PhysicalOptimizer and refactored some of
the code into IndexWhereTaskDispatcher. It follows the patterns of
SkewJoinResolver more closely.
However, this will not run. In IndexWhereProcessor.rewriteForIndex(...) [line
110], we call back to the IndexHandler like before. But, for some reason, the
parseContext we're getting from the physicalContext in IndexWhereResolver does
not have a link back to a SemanticAnalyzer. Any ideas?
I do think that this is correctly making the tasks dependent though.
