> 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 .
