Subject [jira] [Commented] (HIVE-2612) support hive table/partitions coexistes in more than one clusters
Date Tue, 07 Feb 2012 20:15:00 GMT

    [ https://issues.apache.org/jira/browse/HIVE-2612?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13202724#comment-13202724

Namit Jain commented on HIVE-2612:
----------------------------------

Can everyone concerned please take a look ?

For anyone not using clusters, they need to run the scripts provided in this patch to upgrade
the metastore.
The time taken for the upgrade depends on the size of the metastore (number of tables/partitions),
but it should
be fairly small - it is less than 10 minutes for facebook cluster.
