Method Detail

run

public TaskRunner2Result run()

Throws an exception only when there was a communication error reported by the TaskReporter. Otherwise, this takes care of all communication with the AM for a a running task - which includes informing the AM about Failures and Success. If a kill request is made to the task, it will not communicate this information to the AM - since a task KILL is an external event, and whoever invoked it should be able to track it.

Returns:

the taskRunner result

killTask

public boolean killTask()

Attempt to kill the running task, if it hasn't already completed for some other reason.

Returns:

true if the task kill was honored, false otherwise
