Subject [jira] [Commented] (HBASE-7965) Port table locking to 0.94 (HBASE-7305, HBASE-7546, HBASE-7933)
Date Sat, 02 Mar 2013 01:14:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7965?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13591180#comment-13591180

Elliott Clark commented on HBASE-7965:

bq.What is the rolling upgrade story (0.94.5 -> 0.94.7). Does cause any incompatibilities?

At some point the master will be a version that expects the locks to be honored.  The region
servers will be in some indeterminate state.

> Port table locking to 0.94 (HBASE-7305, HBASE-7546, HBASE-7933). This is a new feature,
but there has been some interest, and it is necessary for snapshots, and online merge, which
are also candidates for backport. 
> If we port snapshots, we might need HBASE-7848 as well.
> We can also do disabled by default.
