------------------------------------
Summary: Emit FairCallQueue stats as metrics
Key: HADOOP-15481
URL: https://issues.apache.org/jira/browse/HADOOP-15481
Project: Hadoop Common
Issue Type: Improvement
Components: metrics, rpc-server
Reporter: Erik Krogen
Currently FairCallQueue has some statistics which are exported via JMX: the
size of each queue, and the number of overflowed calls per queue. These are
useful statistics to track over time to determine, for example, if queues need
to be resized. We should emit them via the standard metrics system.
