Subject [jira] [Commented] (HBASE-8081) Backport HBASE-7213 (separate hlog for meta tables) to 0.94
Date Tue, 12 Mar 2013 20:33:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8081?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13600434#comment-13600434
] 

Devaraj Das commented on HBASE-8081:
------------------------------------

[~v.himanshu], good point on the upgrade. There is a risk that if a new server holding the
meta table(s) crashes, the recovery of the meta logs can't be handled by old code. Was discussing
with [~enis] this point offline and it seemed like if we have a boolean config to control
whether to write to a separate hlog for meta (which by default is off) the problem would be
mitigated. But yeah, as [~stack] suggested, let me get the numbers first.

> I am interested in backporting HBASE-7213 to 0.94. Helps to address more of the MTTR
story. Offline discussion with Lars indicated he is interested as well.
