Arpit Agarwal updated HDFS-8820:
--------------------------------
Description: Enabling RPC Congestion control and FairCallQueue settings can
be simplified with HDFS-specific configuration keys. Currently the
configuration requires knowing the exact RPC port number and also whether the
service RPC port is enabled or not separately. If a separate service RPC
endpoint is not defined then RPC congestion control must be enabled. (was: We
propose enabling RPC congestion control introduced by HADOOP-10597 by default.
We enabled it on a couple of large clusters a few weeks ago and it has helped
keep the namenodes responsive under load.)
