JaeHwa Jung updated TAJO-371:
-----------------------------
Description:
Since the default value of the worker memory and the memory required to launch
the query master are same, the worker that launches a query master doesn't have
any free memory without an extra configuration.
In a cluster consisting of one machine, this causes "no available worker
resource for an execution block", and any queries cannot be executed.
Though it is not an error, but it can make users confused.
