[jira] Commented: (HIVE-1427) Provide metastore schema migration scripts (0.5 -> 0.6)

["Carl Steinbach (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-1427?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12891444#action_12891444 ] 

Carl Steinbach commented on HIVE-1427:
--------------------------------------

Here's my plan:

 * Go with the minimal approach of only providing a MySQL upgrade script that upgrades 0.5.0->0.6.0 and 0.6.0->trunk
 * Include changes made here: http://wiki.apache.org/hadoop/Hive/ViewDev#Metastore_Upgrades
 * The scripts will live in metastore/scripts
 * Document the upgrade process in the release notes.

> At a minimum this ticket covers packaging up example MySQL migration scripts (cumulative across all schema changes from 0.5 to 0.6) and explaining what to do with them in the release notes.
> This is also probably a good point at which to decide and clearly state which Metastore DBs we officially support in production, e.g. do we need to provide migration scripts for Derby?
