*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 "
true" 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).
