-------------------------------------
Summary: Propagate task settings to AM when job runs in uber mode
Key: MAPREDUCE-5417
URL: https://issues.apache.org/jira/browse/MAPREDUCE-5417
Project: Hadoop Map/Reduce
Issue Type: Improvement
Components: mrv2
Affects Versions: 2.0.4-alpha
Reporter: Jason Lowe
When a job runs in Uber-AM mode the JVM settings (e.g.: heap sizing), container
sizing, and environment variables are not propagated to the AM. This means
running in uber-AM mode is not as simple as enabling
{{mapreduce.job.ubertask.enable}} since lack of proper heap/container settings
can doom the AM to crash or lack of proper environment variables can prevent
the task code from properly running.
