dhruba requested code review of "[jira][HBASE-5560] Avoid RegionServer GC caused by timed-out calls".
Reviewers: stack, tedyu, sc, JIRA

  A slow client is not consuming rpc responses from the client. But the server caches the call responses uptil 15 minutes (hardcoded). This caused the regionserver to run out of old-gen and trigger a full GC.

  This patch makes the 15 minute value to be settable by a configurable parameter "ipc.client.call.purge.timeout". The default is still 15 minutes to maintain backward compatibility.

TEST PLAN
  Run all unit tests

> The HBaseRpcServer queues up rpc responses if the socket connection to the client is not yet ready to receive data. Calls are queued here until a 15 minute timeout occurs. I am able to generate a full GC when I artificially make a client read rpc-responses very slowly. This jira is to make this 15 minute time configurable.
