[jira] [Created] (TAJO-371) Increase the default value of worker memory

Jihoon Son created TAJO-371:
-------------------------------

             Summary: Increase the default value of worker memory
                 Key: TAJO-371
                 URL: https://issues.apache.org/jira/browse/TAJO-371
             Project: Tajo
          Issue Type: Improvement
          Components: worker
    Affects Versions: 0.8-incubating
            Reporter: Jihoon Son
            Priority: Minor


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.
