----------------------------------------------

Thanks Hitesh. Regarding your questions:
bq. We don't launch the paused container and instead we simply kill it.
bq. Hmm..since we kill the container an event for that will be raised automatically. Am I
missing something?
I understand that you immediately send a kill signal to the process, which is good.
This is sufficient for killing the actual container and reclaiming the resources in the NM,
but it does not let the RM know what happened to the container. Check, for example, the {{ContainerRelaunch}}
or the {{RecoveredContainerLaunch}} classes. Once the container has exited, they send a {{ContainerExitEvent}}.
We should send a similar event once the killing of the paused container is done, setting the
right exit code.

bq. In RecoveredContainerLaunch, indentation needs to be fixed.
My bad, that was a typo -- I meant {{ContainersLauncher}}: we need to fix the indentation
of the case statement.
