Subject [jira] [Commented] (HBASE-15536) Make AsyncFSWAL as our default WAL
Date Fri, 29 Apr 2016 03:15:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15536?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15263462#comment-15263462
] 

Duo Zhang commented on HBASE-15536:
-----------------------------------

There is no plan to backport it to branch-1 currently because of the compatibility issues.
As said in HBASE-14949, if you want to do rolling upgrade to use AsyncFSWAL, then the from
and to versions must both have HBASE-14949 in it, otherwise we may lose data. So it will break
the compatibility guarantee if we backport AsyncFSWAL to branch-1...

I think you can file a backport issue to see what others think of it.

Thanks.
