Walter Su commented on HDFS-9337:
---------------------------------
bq. We need to be careful here while choosing required params.
Good point. And It should be consistent with
[documentation|https://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-hdfs/WebHDFS.html].
bq. We can have a generic method.
Totally agree. That's a good improvement.
To [~jagadesh.kiran], Do you mind merge HDFS-9338 into this. And also check if
there is other required params according to doc, and fix together in this?
Since they do the same thing. It would be helpful to keep the release notes
clean. Thanks for your efforts
