> 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.
