Nick Dimiduk commented on HBASE-13219:
--------------------------------------
>From its description, it seems the default was a single shared connection.
If [~nkeywal] would like to keep the toggle, I suggest we call it --multiCon or
similar, false by default, so the common case is that all client threads share
a single connection.

> -> 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.
