Hi,

When run flink application in yarn mode, is there a way to limit maximum
cpu usage per TaskManager?

I tried this application with just source and sink operator. parallelism of
source is 60 and parallelism of sink is 1. When running in default config,
there are 60 TaskManager assigned. I notice one TaskManager process cpu
usage could be 200% white the rest below 50%.

When I set -yn = 2 (default is 1), I notice # of TaskManger dropped down to
30. and one TaskManger process cpu usage could be 600% while the rest below
50%.

Tried to set yarn.containers.vcores = 2,  all tasks are in start state
forever, application is not able to turn to running state.

Best
Lu
