strange GC behaviour


Hi there,

 

I am running a Beam job with FlinkRunner as a standalone job on YARN with 4 nodes. The job always dies after one hour or two.

Now looking deeper into the task manager metrics, I find that there is a one task manager showing strange CG behavior as shown in the attached screenshots.

 

Can anyone help interpret the numbers under GC?

 

Best,

Zhenhao
