Hi, Flink users

We have recently observed that the allocation of Flink TaskManagers in our
YARN cluster is not evenly distributed. We would like to hear your thoughts
on this matter.

1. Our setup includes Flink version 1.15.1 and Hadoop 2.10.0.
2. The uneven distribution is that out of a 370-node YARN cluster, there
are 16 nodes with either 0 or 1 vCore available, while 110 nodes have more
than 10 vCores available.

Is such behavior expected? If not, is there a fix provided in Flink?
Thanks!

Best
Lu
