> Phase II of the Heterogeneous storage features have completed by HDFS-6584. This JIRA
is opened to enable Quota support of different storage types in terms of storage space usage.
This is more important for certain storage types such as SSD as it is precious and more performant.

> As described in the design doc of HDFS-5682, we plan to add new quotaByStorageType command
and new name node RPC protocol for it. The quota by storage type feature is applied to HDFS
directory level similar to traditional HDFS space quota.
