> "hadoop fs -count -q" or "hdfs dfs -count -q" currently shows name space/disk space quota
and remaining quota information. With HDFS-7584, we want to display per storage type quota
and its remaining information as well.
> The current output format as shown below may not easily accomodate 6 more columns = 3
(existing storage types) * 2 (quota/remaining quota). With new storage types added in future,
this will make the output even more crowded. There are also compatibility issues as we don't
want to break any existing scripts monitoring hadoop fs -count -q output.

> Propose to add -t parameter to display ONLY the storage type quota information of the
directory in the separately. This way, existing scripts will work as-is without using -t parameter.

> 1) When -t is not followed by a specific storage type, quota and usage information for
all storage types will be displayed.

type is displayed.
