--------------------------------
Summary: GroupByContainerIds NPE if containerIds list is null
Key: SAMZA-1347
URL: https://issues.apache.org/jira/browse/SAMZA-1347
Project: Samza
Issue Type: Improvement
Reporter: Jake Maes
Assignee: Jake Maes
Another low-hanging fruit. The null check in group() happens AFTER checking the
size of containerIds. These statements should be reordered.
Also, Since the group(tasks) method always calls the group(tasks, containerIds)
method, lets just move all the safety checks there.
