I am running a Map reduce job which run fine(without Out of Memory) with 8GB map and reduce memory but do have long GC pauses. Currently i am using default JVM. And as G1 is recommended when JVM size grow more than 4GB. I want to know if this will resolve the issue without impacting any other services or Non - Map reduce applications
