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) > --------------------------------------------- > > Key: HDFS-7584 > URL: https://issues.apache.org/jira/browse/HDFS-7584 > Project: Hadoop HDFS > Issue Type: New Feature > Components: datanode, namenode > Reporter: Xiaoyu Yao > Assignee: Xiaoyu Yao > Attachments: HDFS-7584 Quota by Storage Type - 01202015.pdf, > HDFS-7584.0.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
