Seems there are 2067 threads and 1917 of them are something like
"hconnection-0x4f049d87-shared--pool16-t80". Maybe this is the problem.
I do not know where we create a thread with this pattern of name, need to dig
into the code. Is anyone familiar with this part of code?
Thanks.

>
> -> 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.
