Hi all, 
I am trying to insert 100000 records to hbase, each record of size 1kb and 
target 1000 ops/sec using YCSB and I am able to insert the same asynchronously 
without any problem.
But when I enable Coprocessor to inject small validations to the records before 
inserting in to HBase, I get so many time out exceptions. The validation logic 
is not so heavy. 
I have changed rpc handler count to 32 per region server.
I just wanted to understand what is making the Coprocessor so heavy for 
timeouts to occur..



Thanks and regards
Vinay Kashyap
