Jihoon Son created TAJO-1906:
--------------------------------

             Summary: Decrease the default size of hash map and array list for testing
                 Key: TAJO-1906
                 URL: https://issues.apache.org/jira/browse/TAJO-1906
             Project: Tajo
          Issue Type: Task
          Components: Unit Test
            Reporter: Jihoon Son
            Assignee: Jihoon Son
             Fix For: 0.12.0, 0.11.1


The default size of hash maps and array lists for aggregation, sort, or join is at least 10000, but the number of tuples is much smaller that it in most of our tests.
Thus, most spaces for those data structures are not used during tests. We need to reduce such unnecessary memory usage.
