better way to write the testcase.

$ ./hdfs storagepolicies -setStoragePolicy -path /BBP -policy COLD
Set storage policy COLD on /BBP
{noformat}
*without Patch*
{noformat}
host1 bin# ./hdfs storagepolicies -getStoragePolicy -path /BBP
The storage policy of /BBP is unspecified
{noformat}
*with Patch*
{noformat}
host1 bin# ./hdfs storagepolicies -getStoragePolicy -path /BBP
The storage policy of /BBP:
BlockStoragePolicy{COLD:2, storageTypes=[ARCHIVE], creationFallbacks=[],
replicationFallbacks=[]}
{noformat}
