--------------------------------

             Summary: Enable Quota Support for Storage Types (SSD) 
                 Key: HDFS-7584
                 URL: https://issues.apache.org/jira/browse/HDFS-7584
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Xiaoyu Yao
            Assignee: Xiaoyu Yao


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.
