[MAPREDUCE-6702] TestMiniMRChildTask.testTaskEnv and TestMiniMRChildTask.testTaskOldEnv are failing

• Type: Bug
• Status: Resolved
• Priority: Major
• Resolution: Fixed
• Affects Version/s: 3.0.0-alpha1
• Component/s: client
• Target Version/s: 3.0.0-alpha1
• Hadoop Flags: Incompatible change, Reviewed

Release Note

<!-- markdown -->
In Hadoop 3, YARN containers do not inherit the NodeManagers' environment variables. Therefore, if you want to inherit NodeManager's environment variables (e.g. `HADOOP_MAPRED_HOME`), you need to set additional parameters (e.g. `mapreduce.admin.user.env` and `yarn.app.mapreduce.am.env`).
