Dheeraj Kumar Singh updated HIVE-4095:
--------------------------------------
Status: Patch Available (was: Open)
This diff adds an exchange partition feature to hive. The command is of the
following format:
ALTER TABLE <source_table_name> EXCHANGE PARTITION <partition> WITH TABLE
<dest_table_name>
This only works if <source_table_name> and <dest_table_name> have the same
field schemas and the same partition by parameters. If they do no the command
will throw an exception.
This will take the partition from <partition> from <source_table_name> and will
do an HDFS rename of the partition folder so that the partition now belongs to
<dest_table_name>. It will also change the metadata to show that partition
of <source_table_name> has been deleted and added to <dest_table_name>.
