I originally created this JIRA focusing on the reservation support, but realized that this
didn't align with my [original proposal|https://issues.apache.org/jira/browse/HADOOP-15016?focusedCommentId=16673288&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16673288],
so updated the summary/description to reflect that this JIRA should be for the cost-based

> 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

to more specifically focus on the reservation portion of the work.
