-------------------------------------
I have some more recent results, both for multiwal settings by themselves and
in conjunction with ALL_SSD for hte WALs. Let me try to get them cleaned up an
sharable.
> Turn on multi-WAL by default

> Key: HBASE-15131
> URL: https://issues.apache.org/jira/browse/HBASE-15131
> Project: HBase
> Issue Type: New Feature
> Components: wal
> Reporter: Enis Soztutar
> Fix For: 2.0.0, 1.3.0
>
>
> 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?
