Subject [jira] [Commented] (HBASE-7965) Port table locking to 0.94 (HBASE-7305, HBASE-7546, HBASE-7933)
Date Mon, 18 Mar 2013 21:51:15 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7965?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13605707#comment-13605707
] 

Jonathan Hsieh commented on HBASE-7965:
---------------------------------------

I think it is unfair to claim that the ability to change schema without disabling the table
is a feature that is required to for HBase to be production ready.   

The feature is it is off by default, essentially documented as experimental ({{"Its off by
default. Enable it at your own risk."}} [1]), so in my eyes fixing it essentially feels like
a new feature.

(Sorry for the delay, was away for a 2 weeks).

> 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.
