Hive Slide 98?
For newly created tables and/or partitions (that are populated through the INSERT OVERWRITE command), statistics are automatically computed by default. The user has to explicitly set the boolean variable hive.stats.autogather to false so that statistics are not automatically computed and stored into Hive MetaStore.
