Hi Qi,
The current version of PR is runnable in production. But according to Till's suggestion, It needs one more round of change.
Best Regards

Hi Qi,
I think the problem may be related to another similar problem reported in a previous JIRA [1]. I think a PR is also in discussion.
Thanks,

Hello,
Today we encountered an issue where our Flink job request for Yarn container infinitely. In the JM log as below, there were errors when starting TMs (caused by underlying HDFS errors). So the allocated container failed and the job kept requesting for new containers. The failed containers were also not returned the the Yarn, so this job quickly exhausted our Yarn resources.
Is there any way we can avoid such behavior? Thank you!
