Subject [jira] [Commented] (HBASE-7213) Have HLog files for .META. edits only
Date Tue, 27 Nov 2012 06:35:59 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7213?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13504398#comment-13504398

Devaraj Das commented on HBASE-7213:
------------------------------------

Apologies for not responding earlier.. But yes, the high level idea is to make the recovery
of META table fast and hence reduce the downtime of META should the regionserver hosting the
RS crash. By having a dedicated HLog for META, the log splitting will be really simple (maybe
just simple rename operations of files; need to look at the code here)...

I am in the middle of plumbing through the code to make this work. Will hopefully have something
in a day or two.

> Over on HBASE-6774, there is a discussion on separating out the edits for .META. regions
from the other regions' edits w.r.t where the edits are written. This jira is to track an
implementation of that.
