Subject [jira] [Commented] (HIVE-16344) Test and support replication of exchange partition
Date Wed, 19 Apr 2017 08:57:41 GMT

    [ https://issues.apache.org/jira/browse/HIVE-16344?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15974341#comment-15974341
] 

Lefty Leverenz commented on HIVE-16344:
---------------------------------------

[~sushanth], please help me understand the difference between pull requests and commits. 
A comment above shows a pull request with commit number 9f05ce306be94699dece614de164fb7fd460b8bd
but the commits mailing list has a different commit number (a38ae17fea04b25f83c3553d76c550fed4561efa)
for the same patch.  What's the difference?  In github, the latter commit is shown for the
code changes.

Anyway, the commit on the commits mailing list gives the JIRA number of the parent issue (HIVE-14841)
instead of this issue (HIVE-16344).  So an entry in errata.txt is needed to clarify the JIRA
number.  See HIVE-11876 for an example of updating errata.txt.

> The Exchange (Move) partition operation should be replicated.
> -- Move partition from src_table to dest_table
> ALTER TABLE dest_table EXCHANGE PARTITION (partition_spec) WITH TABLE src_table;
> -- multiple partitions
> ALTER TABLE dest_table EXCHANGE PARTITION (partial_partition_spec) WITH TABLE src_table;
> Already, logging the Exchange Partition as ADD_PARTITION event on destination table and
DROP_PARTITION event on source table.
> Need to check the behaviour and then also add a test to verify the same.
