> 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.
