If we need to separate out the 'secured' code block, can we do that in all
scenarios instead of the conditional logic here? For example, move the block
on lines 138-147 to a new method, and pass a method reference to
`runTaskManager` as the callable.

> The local keytab path in YarnTaskManagerRunner is incorrectly set to the
> ApplicationMaster's local keytab path. This causes jobs to fail because the
> TaskManager can't read the keytab.
