Review request for hive and John Pullokkaran.

Repository: hive-git


Hive will collect table stats when set hive.stats.autogather=true during the INSERT OVERWRITE
command. And then the users need to collect the column stats themselves using "Analyze" command.
In this patch, the column stats will also be collected automatically when a flag is set.
