[Discuss] : Container JVM reuse feature for MRv2.

[Rohith Sharma K S]

Hi folks

     I would like to know, Is there any feature exists for container JVM reuse 
within the same task types MRv2.? I  see some Open Jira's(MAPREDUCE-3902, 
MAPREDUCE-4502) related to this feature, but I don't see any of these are 
available in any of released versions or

trunk. Is there separate branch for MAPREDUCE-3902. ? It will be more useful if 
this feature available in MRv2.

Thanks & Regards
