Review request for hive and John Pullokkaran. Repository: hive-git Description ------- 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.
