@InterfaceAudience.Private
public class CompleteDelegator
extends TempletonDelegator

Complete a job. This will run the callback if - the job is done - there is a callback - the callback has not yet been called There is a small chance for a race condition if two callers run this at the same time. That should never happen. We use a Hadoop config var to notify this class on the completion of a job. Hadoop will call us multiple times in the event of failure. Even if the failure is that the client callback failed. See LauncherDelegator for the HADOOP_END_RETRY* vars that are set.
