> 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 ([see comment|https://issues.apache.org/jira/browse/HDFS-8820?focusedCommentId=14987848&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14987848] from [~mingma] below.
