Subject Re: HBase concurrent.RejectedExecutionException
Date Wed, 19 Nov 2014 17:21:25 GMT
Hi Arul,

It's a pure client exception: it means that the client has not even tried
to send the query to the server, it failed before.
Why the client failed is another question.
I see that the pool size is 7, have you changed the default configuration?

Cheers,

Nicolas
