zhangduo commented on HBASE-13219:
----------------------------------

Set RpcClientFactory.CUSTOM_RPC_CLIENT_IMPL_CONF_KEY to RpcClientImpl.class and 
try again?
And maybe we could try to get a thread dump then it is more clear if there are 
thread leaks.

> -> PE tool tries to create the TEstTable and waits for it to be enabled and 
> just hangs there 
> Previously this was not happening and the PE tool used to run fine after the 
> table creation.
> -> When we try to scan with 25 threads the PE tool fails after some time 
> saying Unable to create native threads.
> I lost the Stack trace now. But I could get it easily.  It happens here 
> {code}
>   public void submit(RetryingCallable<V> task, int callTimeout, int id) {
>     QueueingFuture<V> newFuture = new QueueingFuture<V>(task, callTimeout);
>     executor.execute(Trace.wrap(newFuture));
>     tasks[id] = newFuture;
>   }
> {code}
> in ResultBoundedCompletionService. This is also new.  Previously it used to 
> work with 25 threads without any issues.
