Sorry I did not quite understand the problem.

Do you mean a failed job does not release resources to yarn? 

 - if so, is the job in restarting process? A job in recovery will reuse the slots so they will not be release.

Or a failed job cannot acquire slots when it is restarted in auto-recovery?

- if so, normally the job should be in a loop like (restarting tasks -> allocating slots -> failed due to not be able to acquire enough slots -> restarting task -> ...). Would you check whether the job is in such a loop? Or the job cannot allocate enough slots even if the cluster has enough resource?

Thanks,

Zhu Zhu

Hi,

    Recently, I find a problem when job failed in 1.10.0, flink didn’t release resource first.

  

     You can see I used flink on yarn, and it doesn’t allocate task manager, beacause no more memory left. 

     If i cancel the job, the cluster has more memory.

     In 1.8.2, the job will restart normally, is this a bug?

     Thanks.
