------------------------------------

             Summary: Cleanup StreamTaskStates if a checkpoint operation of a subsequent operator fails
                 Key: FLINK-5229
                 URL: https://issues.apache.org/jira/browse/FLINK-5229
             Project: Flink
          Issue Type: Bug
          Components: State Backends, Checkpointing, TaskManager
    Affects Versions: 1.1.3, 1.2.0
            Reporter: Till Rohrmann
            Assignee: Till Rohrmann
             Fix For: 1.2.0, 1.1.4


Due to chaining, a {{StreamTask}} needs to checkpoint multiple operators. If the first operators succeed in creating a checkpoint but a subsequent operator in the chain fails, the {{StreamTask}} has to clean up the already completed checkpoints. Otherwise we might end up with orphaned state data.
