> Project: Hadoop Map/Reduce

> Priority: Minor

>
> The SortValidator.java file checkRecords method creates a file in the
> /tmp/sortvalidator directory using a static filename. This can result in
> failures due to name collisions when the
> hadoop-mapreduce-client-jobclient-*-tests jar is used by more than one task
> or one user simultaneously. We use this jar when testing compression codecs
> and after we started running tests in parallel (four at a time to reduce
> overall test time) we started experiencing random test failures due to name
> collisions. Creating a random or unique per thread filename may resolve this
> issue. We have developed a change to introduce per use unique file names.
