Subject [jira] [Created] (FLINK-6182) Fix possible NPE in SourceStreamTask
Date Fri, 24 Mar 2017 11:23:41 GMT
Ufuk Celebi created FLINK-6182:

             Summary: Fix possible NPE in SourceStreamTask
                 Key: FLINK-6182
                 URL: https://issues.apache.org/jira/browse/FLINK-6182
             Project: Flink
          Issue Type: Bug
          Components: Local Runtime
            Reporter: Ufuk Celebi
            Priority: Minor

If SourceStreamTask is cancelled before being invoked, `headOperator` is not set yet, which
leads to an NPE. This is not critical but leads to noisy logs.
