> Something to discuss for 2.0 or even 1.3 or 1.4. Should we turn on multi-WAL by default now that it has seen some production use. 
> Most of the known issues has been fixed I believe for replication, metrics etc. See HBASE-14457. 
> Using bounded provider with default 4 (assuming 12 disks). Should we also look at the number of disks from datanode dirs and auto-configure?
