Zhe Zhang commented on HDFS-10789:
----------------------------------
Thanks much for working on this [~daryn] [~kihwal] and [~shahrs87].
One feature we want is for WebHDFS calls to be restricted under the RPC ACLs
(e.g. revoking a certain user's permission to issue certain WebHDFS calls). I
haven't look into much detail of the patch. Any quick answer on this? Thanks!

> Webhdfs is extremely expensive under load and is not subject to the QoS
> benefits of the RPC call queue. HADOOP-13537 provides the basis for routing
> webhdfs through the call queue to provide unified QoS.
