Subject [jira] [Commented] (HBASE-13017) Backport HBASE-12035 Keep table state in Meta to 1.0 branch
Date Wed, 11 Feb 2015 23:05:12 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13017?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14317167#comment-14317167

Andrey Stepachev commented on HBASE-13017:
------------------------------------------

Current state is:
1. we have migration (server automatically gather states from zk and apply them to META, defaults
to ENABLED)
2. clients will not see disabled status, that is because they go to zk directly but status
updated in meta. 
3. enable/disable rpc calls should work due of the fact, that master is responsible for enablding/disabling
tables and
master should be upgraded. 
4. rolling upgrade can be tricky, RS will use zk for table status checks, but generally there
should be no admin
operations during rolling update, so I think that that will not be an issue.

looks like unless old client not used for admin operations with table
states most things should work.
