------------------------------------

             Summary: Allow specifing java home via job configuration
                 Key: MAPREDUCE-6687
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6687
             Project: Hadoop Map/Reduce
          Issue Type: New Feature
          Components: applicationmaster
            Reporter: He Tianyi
            Priority: Minor


Suggest allowing user to use a preferred JVM implementation (or version) by specifying java
home via JobConf, to launch Map/Reduce tasks. 

Especially useful for running A/B tests on real workload or benchmark between JVM implementations.
