Review request for Tajo.
Bugs: TAJO-628
https://issues.apache.org/jira/browse/TAJO-628
Repository: tajo
Description
-------
Distinct aggregation requires three stages. But, the second stage can be
scheduled to one node due to wrong counting of grouping keys.
This patch fixes this bug. In addition, this patch fixes some trivial bugs in
Task.java that I found during this debugging.
