> On 3.0.0.alpha1 , contain "Remove parent's env vars from child processes " which commit
by [#Robert Kanter] ,but it's seem not found in jira or release note. DefaultContainerExecutor
& DefaultLinuxContinerExecutor default the 'inheritParentEnv' as false,there is no any
approach to set the "HADOOP_MAPRED_HOME" ,the AM failed by "Could not find or load main class
org.apache.hadoop.mapreduce.v2.app.MRAppMaster"
