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

             Summary: Task launching blocked due to pending on #waitForChannel after failover
                 Key: FLINK-13254
                 URL: https://issues.apache.org/jira/browse/FLINK-13254
             Project: Flink
          Issue Type: Bug
          Components: Runtime / Network
    Affects Versions: 1.9.0
            Reporter: Zhu Zhu
         Attachments: pendingOnDeploying.log, task_counts2.stack

We observed that a task will remain in DEPLOYING forever, pending on waiting for channel at TM side.

Sample log is attached, including the TM log and stack for task "Sink: counts2 (1/20)".

 

This case happens after a region failover, which might be related.
