> does not work, because fs is not a LocalFS, but an HFS. And HFS internally
> does not do this check. seStoragePolicy() is very HDFS specific, the logic
> should instead check whether the underlying fs is HDFS (as opposed to
> checking whether it is not local FS). There are file systems that HBase
> supports other than local or HDFS.
