> I reported this problem in our dev mailing list before
> (http://mail-archives.apache.org/mod_mbox/tajo-dev/201410.mbox/%3CCACZfFK743PCEJkz0=rdt0ltuw-ajatyopgunsmragprhfc7...@mail.gmail.com%3E),
> and finally found where the problem is caused.
> The problem is, when a task runner requests a task via
> QueryMasterProtocolService.Interface.getTask(), the query master task is not
> started yet, so QueryMasterManagerService sends 'stopTaskRunnerReq' as a
> reply to that request.
> This asynchronous problem may be prominent in quite slow machines.
> I'm thinking solutions, but don't still have any ones.
> Do you have any good idea?
