> Currently, in the NodeManager's serviceInit() function, the configured executor is initialized
before the node health checker/directory handler service are initialized. There are use cases
where executor initialization requires access to 'good' local directories ( e.g for creation
of temporary files , see YARN-3366 ).  We need to figure out a way to make this possible.
