*If I kill the child process * So are you observing that a replacement container instance is never started? Can you check the AM log? What is expected to happen here is as follows: - process goes down, and then agent goes down, AM notices, asks for a new container from Yarn.
if you want the agent to restart the process then you need to set " <autoStartOnFailure>true</autoStartOnFailure>" for the component in the metainfo.xml. This is not part of 0.40 though. *If I kill the agent process* This is YARN-1922 (https://issues.apache.org/jira/browse/YARN-1922).
