Yes I put it in my input operator, do I need to do anything or make sure there’s anything
specific in the other operators?

Have you thrown it in all input operators? It starts from the operator you throw it in and
propagates downstream. All operators need to shutdown before application changes state.

The ShutdownException does stop the operator but doesn’t seem to update the state of the
application, still in the RUNNING state.  Is there something specific I need to put in the
endwindows or teardowns?

Just one additional information to what Sandesh said. ShutdownException shuts down the operator
from which its thrown and all downstream operators to that operator.
Hence if you want the DAG to shutdown completely, you need to throw ShutdownException from
all *input* operators.

Hello Austin,

Throwing ShutdownException  from the operators will shutdown the Apex Application.

When would an Apex Application return a FINISHED status from YARN as opposed to continually
being in the RUNNING state?
Is there a way to force the YARN status to FINISHED from within the application when processing
is complete?
