> As the review comment in HDFS-7323. 
> In {{StoragePolicyAdmin}} and other class under {{org.apache.hadoop.hdfs.tools}}, such
as {{CacheAdmin}}, {{CryptoAdmin}}. There are too many common methods ({{getDFS}}, {{prettifyException}},
{{getOptionDescriptionListing}} ...) and also inner class ({{HelpCommand}}), they are the
same, it would be great if we can refine and shift them into a common place.
> This makes the code clean and can be re-used if we add new hdfs admin class in future.
