(Updated 2011-08-19 20:20:22.217903)
Review request for hive, Yongqiang He, John Sichi, and Ning Zhang.
Changes
-------
Moves a bunch of the logic to update index timestamps into the AlterIndex
DDLTask rather than the DDLSemanticAnalyzer, so that the timestamp is
guaranteed to be updated *after* the base table is touched. This change is
reflected in index_auto_update.q, as now we see that the check for index
staleness in the SELECT passes and we use the index in index_auto_update.q as
desired.
Summary
-------
Chain a second set of tasks to the MoveTask for INSERT statements.
This addresses bug HIVE-2354.

> 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.
