Phabricator updated HBASE-5560:
-------------------------------
Attachment: D2241.1.patch
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.
