Xiaoyu Yao commented on HDFS-7584:
----------------------------------
Attach a preliminary patch to demo the proposal. I will open separate JIRAs for
# Add option to display quota by storage type info in hadoop shell command
"hadoop fs -count -q", this requires StorageType.java being moved from
hadoop-hdfs to hadoop-common.
# Update the editsStored for TestOfflineEditsViewer for new
SetQuotaByStorageType op.
# Adding more unit tests for quota by storage type, more specifically on
snapshot and checkpoint.
> Enable Quota Support for Storage Types (SSD)

> 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.
