> In our cluster, we has many SSD and a little HDD.  (Most table configured 
> storage policy ONE_SSD, and all wals is configured ALL_SSD)
> when all cluster down, It's difficult to recovery cluster. Because HDD Disk 
> IO bottleneck (Almost all disk io util is 100%).
> I think the most hdfs operation when recovery is split wal to recovered edits 
> dir, And read it.
> And it goes better when i stop hbase and set all recovered.edits to ALL_SSD.
> So we can get benifit of recovery time if we set recovered.edits dir to 
> better storage like WAL.
> Now i reuse config item  hbase.wal.storage.policy to set recovered.edits 
> storage type. Because I did not find a scenario where they use different 
> storage Policy
