[jira] [Comment Edited] (HDFS-14403) Cost-Based RPC FairCallQueue

    [ https://issues.apache.org/jira/browse/HDFS-14403?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16907612#comment-16907612 ]

Just backported this into branch-3.2 ~ branch-3.0 as part of HDFS-14667. The only real difference in the backport was that {{FairCallQueue.md}} doesn't exist in branch-3.2 and below, so I did not backport the documentation changes as part of this.

> HADOOP-15016 initially described extensions to the Hadoop FairCallQueue encompassing both cost-based analysis of incoming RPCs, as well as support for reservations of RPC capacity for system/platform users. This JIRA intends to track the former, as HADOOP-15016 was repurposed to more specifically focus on the reservation portion of the work.
