Subject [jira] [Commented] (TEZ-2024) TaskFinishedEvent may not be logged in recovery
Date Wed, 04 Feb 2015 00:35:36 GMT

---------------------------------

[~hitesh] Will add unit test.

bq. Shouldn't the end event always be logged to timeline/history even if a start event was
not generated?
It looks like the current logic is that one FinishedEvent must be associated with one StartedEvent,
the same as TaskAttempt. I also think it doesn't make sense to do that, Task can finish before
it is started. How about extending the scope of this jira to fix this ?

{code}
        if (!recoveryStartEventSeen) {
          throw new RuntimeException("Finished Event seen but"
              + " no Started Event was encountered earlier");
        }
{code}
