Hyunsik Choi commented on TAJO-648:
-----------------------------------
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
