----------------------------------------------------

Hi [~chia7712], 

 Thank you for your comments. As suggested, I have added a new class CallQueueInfo.java to store the queue information. I have also included tests for SimpleRpcScheduler and FifoScheduler. Kindly let me know if it looks OK now. 

Old patch is renamed to 0001-Dump-call-queue-summaries.patch.old.  Current patch is 0001-Changes-for-HBASE-16290.patch.

Thanks,
Sreeram

> Being able to get a clue what is in a backedup callQueue could give insight on what is going on on a jacked server. Just needs to summarize count, sizes, call types. Useful debugging. In a servlet?
