Subject Co Processor taking more time to process the request ?
Date Wed, 30 Nov 2016 18:09:44 GMT
Dear All,
We are using the Coprocessor to fetch the records from the HBase .There are
3 Region Servers present each having 60 regions currently ,
But when we call the coprocessor it making making a call to all the
regions(I think it is obvious with coprocessor).
But as the each Region Server is getting the 60 RPC calls the time taken to
process the last regions is increasing always .
Result of it the over all time taken by coprocessor is more few seconds .

Example :
Rpc Request. Time Taken in Seconds
[B.defaultRpcServer.handler=46,queue=4,port=16020]  20
[B.defaultRpcServer.handler=24,queue=0,port=16020]  10
[B.defaultRpcServer.handler=40,queue=4,port=16020]   4
[B.defaultRpcServer.handler=33,queue=3,port=16020]   4
[B.defaultRpcServer.handler=38,queue=2,port=16020]   3
[B.defaultRpcServer.handler=38,queue=2,port=16020]   3
[B.defaultRpcServer.handler=49,queue=1,port=16020]   2
[B.defaultRpcServer.handler=7,queue=1,port=16020]    1

Could some please explain .
Why it taking more time for the last RPCs .
What does B.defaultRpcServer.handler=46,queue=4,port=16020 mean in the
Region Server log.
Thanks in Advance,
Param.
