Sreeram Venkatasubramanian updated HBASE-16290:
-----------------------------------------------
    Status: Patch Available  (was: In Progress)

Hi Chia-Ping Tsai,

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?
