Andrew Purtell commented on HBASE-18118:
----------------------------------------
I came here and did this because of log spew. Exceptions from HDFS. Perhaps
something has changed. As long as that does not happen again I'm not concerned.
> Default storage policy if not configured cannot be "NONE"

> HBase can't use 'NONE' as default storage policy if not configured because
> HDFS supports no such policy. This policy name was probably available in a
> precommit or early version of the HDFS side support for heterogeneous
> storage. Now the best default is 'HOT'.
