Subject [Hadoop Wiki] Update of "Hive/StatsDev" by ahmedaly
Date Thu, 29 Jul 2010 19:34:22 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.

The "Hive/StatsDev" page has been changed by ahmedaly.


  == Usage ==
- === Newly created tables ===
+ === Newly Created Tables ===
  For newly created tables and/or partitions (that are populated through the [[http://wiki.apache.org/hadoop/Hive/LanguageManual/DML#Inserting_data_into_Hive_Tables_from_queries|
INSERT OVERWRITE]] command), statistics are not automatically computed by default. The user
has to explicitly set the boolean variable '''hive.stats.autogather''' to '''true''' so that
statistics are automatically computed and stored into Hive MetaStore.
  set hive.stats.autogather=true;
