Date Sat, 23 Apr 2011 06:49:05 GMT


Russell Melick updated HIVE-1644:

    Attachment: HIVE-1644.16.patch

Patch 16

One last problem.  It doesn't appear the index is actually used.  I tried looking a little
bit at the hadoop logs, but I don't really know what I'm looking for.  I left a comment on
the reviewboard.

scan.  The next step is to use these for selecting available indexes and generating access
plans for those indexes.
