Subject [jira] [Commented] (HBASE-7213) Have HLog files for .META. edits only
Date Sat, 12 Jan 2013 19:56:12 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7213?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13552031#comment-13552031
] 

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

bq. For the first if statement above, should we check whether this.hlog is null ? If this.hlog
is null, we should be calling this.hlogForMeta.closeAndDelete().

I don't think we need to worry about it. We will not have a case where _hlogForMeta_ is non-null
and _hlog_ is null (_hlog_ is initialized before _hlogForMeta_).

> 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.
