Failing a DAG based on thrown exception

["McCullough, Alex" <Al...@capitalone.com>]

Hey All,

Operators that are based on an underlying data store, when trying to connect in setup or activation, if an exception is thrown I would like to fail the app as a whole. My understanding is that if I don’t handle the exception, the operator will just continually be killed and restarted and the app as a whole may continue to run. First of all is this correct?  If so, how can I force the app to a failed status if certain exceptions are thrown or conditions are met?

Try throwing a ShutdownException (in Operator.java)

To force the app to shutdown you can you can throw a ShutdownException. See https://lists.apache.org/thread.html/e84f3fec5cc84b21b4547463c4a93f10b04dbdc92fb38d9f6283442c@%3Cusers.apex.apache.org%3E
