Hi Vinod, The heap size is 40GB and NewRatio is set to 3. We have max completed applications set to 100000.

Full GC (with Parallel GC, 8 threads) is sometimes taking more than 30 sec due to which state store sessions to Zookeeper time out resulting in FATAL errors. The YARN cluster is heavily used with 1000’s of applications launched per hour. Could you please share any documentation related to best practices for tuning resourcemanager GC? Thanks, Puneet
