What is recommended configuration for "G1GC" in Resource Manager

Explorer

I am running ResourceManagerin the following environment,

2CPU/64GBMEM/4TB

OS Linux6.5, JDK 1.8

ResourceManager sometimes takes much time to Full GC.

・ORACLE tutorials.Getting started with the G1 GarbageCollector

・ORACLE G1GC turning

https://docs.oracle.com/javase/8/docs/technotes/guides/vm/gctuning/g1_gc_tuning.html#sthref61

As per my current undetstanding, the possible fix forthis could be G1GC.

I have gone through few documents.However, I am unable to understand it in detail.

Does anyone know recommended values to be configured for G1GC inResource-Manager?

Which key will be used for G1GC,and how will each key be used?

G1 is not fully tested and supported on hadoop framework, you can follow the article https://community.hortonworks.com/articles/14170/namenode-garbage-collection-configuration-best-pra.... to know about different GC collector configuration.

@Rajkumar Singh

Thank you for your reply. I had refered to this article before posting this question.

As I couldn't manage heap memory using recommended CMS Configuration mentioned in the article, I'm investigating more into the use of G1 in HadoopFramework.
