[jira] [Created] (KAFKA-4427) Skip topicGroups with no tasks

Eno Thereska created KAFKA-4427:
-----------------------------------

             Summary: Skip topicGroups with no tasks
                 Key: KAFKA-4427
                 URL: https://issues.apache.org/jira/browse/KAFKA-4427
             Project: Kafka
          Issue Type: Bug
          Components: streams
    Affects Versions: 0.10.2.0
            Reporter: Eno Thereska
            Assignee: Eno Thereska
             Fix For: 0.10.2.0


Currently the StreamPartitionAssignor's "assign" method does not handle cases where we don't have tasks for a particular topic group. E.g., code like this might give an NPE:
"for (TaskId task : tasksByTopicGroup.get(topicGroupId))" 

We need to handle the above cases.
