Apache Flink - How to get heap dump when a job is failing in EMR

[M Singh]

Hi:

Is there any configuration to get heap dump when job fails in an EMR ? 

Thanks

I think it depends on the root cause of your job failure. Maybe the following jvm options could help you to get the heap dump.

1. -XX:+HeapDumpOnOutOfMemoryError

2. -XX:+HeapDumpBeforeFullGC

3. -XX:+HeapDumpAfterFullGC

4. -XX:HeapDumpPath=/tmp/heap.dump.1

Use env.java.opts to set java opts for all flink JVMs, including JM and TM . 

Use env.java.opts.jobmanager for JM and env.java.opts.taskmanager for TM.

Best,

Yang
