Dear Wiki user,

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

The "Hive/LanguageManual/DDL" page has been changed by JohnSichi.

exactly matches the existing key_value_store in all particulars other than table name.  The
new table contains no rows.
  
  ==== Inserting Data Into Bucketed Tables ====
- The CLUSTER BY and SORTED BY creation commands do not affect how data is inserted into a
table -- only how it is read.  This means that users must be careful to insert data correctly
by specifying the number of reducers to be equal to the number of buckets, and using CLUSTER
BY and SORT BY commands in their query.

  There is also an [[Hive/LanguageManual/DDL/BucketedTables|example of creating and populating
bucketed tables]].
