> 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.
