> 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.
