> testSpeculateSuccessfulWithUpdateEvents fails Intermittently
> --------------------------------------------------------------
>
> Key: MAPREDUCE-7259
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-7259
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Reporter: Ahmed Hussein
> Assignee: Ahmed Hussein
> Priority: Minor
> Attachments: MAPREDUCE-7259.001.patch
>
>
> {{TestSpeculativeExecutionWithMRApp.testSpeculateSuccessfulWithUpdateEvents}}
> fails Intermittently with the exponential estimator. The problem happens
> because assertion fails waiting for the MRApp to stop.
> There maybe a need to redesign the test case because it does not work very
> well because of the racing and the timing between the speculator and the
> tasks. It works fine for the legacy estimator because the estimate is based
> on start-end rate.
