        • Priority: Minor
        • Resolution: Fixed

          Description

          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.

              FLINK-6182 Fix possible NPE in SourceStreamTask

              A user ran into this and reported confusing NPEs in the logs. This could only happen if a source task is cancelled before it was invoked.
