        This issue got +1 on RB. I've committed this patch to master.

        After this patch, web UI may not show the number of running queries. As you can see TAJO-540 and TAJO-654 , scheduler, resource manager and worker will be changed significantly for a while. So, they can be unstable for a while.

        The bug is a known bug. The current trunk has the bug caused by the recent refactoring. Actually, I'm currently fixing the bug you reported.

        In contrast, we are preparing the release of 0.8.0. So, branch-0.8.0 is stable.

        You can see the branch at below link:

        You can checkout the branch-0.8.0 as follows:

        git clone -b branch-0.8.0 https://git-wip-us.apache.org/repos/asf/incubator-tajo.git
        

        Thanks for your report!

        Hi Guo,

        According to the log message, there are no workers which are joined to the Tajo cluster. Could you check the joined workers? You can see them via web UI at http://tajomaster_hostname:26080/.

        If there are no available workers, please take a look at the worker log at $

        {TAJO_ROOT}

        /logs.

        Thanks,
        Hyunsik
