Subject [jira] [Commented] (HDFS-8631) WebHDFS : Support get/setQuota

Andrew Wang commented on HDFS-8631:
-----------------------------------

Hi [~surendrasingh],

I did some digging into the history, as the asymmetry between FileSystem#getQuota and HdfsAdmin#setQuota
seemed intentional. Sure enough, there's a discussion on HDFS-3000.

It sounds like we want to expose the HDFS-specific functionality in HdfsAdmin via a REST interface.
However, we need to do this without expanding the FileSystem interface, since the HdfsAdmin
functionality is HDFS-specific. So, we need to define a separate WebHdfsAdmin separate from
WebHdfsFileSystem. The server-side functionality can still be implemented with the same NN
and DN servlets.

We also need to document these WebHdfsAdmin APIs specially, perhaps in a new page that separates
them from the FileSystem APIs.

> User is able do quota management from filesystem object. Same operation can be allowed
trough REST API.
