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

             Summary: Connection timeout occurs while checkpointing
                 Key: FLINK-14697
                 URL: https://issues.apache.org/jira/browse/FLINK-14697
             Project: Flink
          Issue Type: Bug
          Components: Runtime / Checkpointing
    Affects Versions: 1.8.0
         Environment: Flink version : 1.8.0

Yarn cluster mode

8 nodes

16 yarn containers
            Reporter: dmgkeke


I am currently running a flink streaming application.

It generally works well.

But I have one issue.

Intermittently connection timeout occurs on netty during a checkpoint.

And restarting app by failover strategy

All nodes are not busy, Network traffic is also normal.

But I can't find a solution for this situation.

Please let me know how to solve the problem.

I have written the log trace below.
