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.

> HIVE-1226 provides utilities for analyzing filters which have been pushed down to a table scan.  The next step is to use these for selecting available indexes and generating access plans for those indexes.
