>
> During investigation of HBASE-20723, I realized that we wouldn't get the best
> performance when hbase.wal.dir is configured to be on different (fast) media
> than hbase rootdir w.r.t. recovered edits since recovered edits directory is
> currently under rootdir.
> Such setup may not result in fast recovery when there is region server
> failover.
> This issue is to find proper (hopefully backward compatible) way in
> colocating recovered edits directory with hbase.wal.dir .
