--------------------------------
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.
