    Resolution: Invalid

due to local changes, it made an assumption to raise outside of create()

>             Project: Aurora
>          Issue Type: Bug

> if https://github.com/apache/aurora/blob/master/src/main/python/apache/aurora/executor/common/sandbox.py raises any exceptions then thermos_executor continues to run but no longer responds to any commands.  It's orphaned and continues to consume resources until manually killed.
> Based on conversation with Maxim on #aurora, the correct action is likely to catch https://github.com/apache/aurora/blob/master/src/main/python/apache/aurora/executor/aurora_executor.py#L122 and exit appropriately.
> To reproduce attempt to launch as a non-exist user on the slave, or causing a chmod/chown failure which will raise CreationError.  Once this occurs one will see that aurora UI never passes state STARTING.  When transient_task_state_timeout is reached then the task state moves to LOST.  thermos_executor will be still running on the slave and mesos considers the task still active and state is STARTING.  Unfortunately GC will be unable to clean it up as it does not know about it.  At this point there is nothing to recover this orphaned thermos_executor short of killing it by hand.
> Sorry the line numbers will not match due to local changes, but the stacktrace should be accurate.
