Syed S. Albiz commented on HIVE-2354:
-------------------------------------
Actually, looking more closely at the testcase output, there is an issue with
this patch. The timestamps set when the index is rebuilt are still coming up
stale, so we don't see index usage in the EXPLAIN plan of the SELECT query. I
will investigate further
> Support automatic rebuilding of indexes when they go stale

> Support a mode where indexes will be automatically rebuilt when the
> table/partition they are based on is modified. So if index foo is built on
> table bar, and bar has it's contents overwritten, we should support a mode
> where index foo will automatically rebuild itself.
