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.
