Mark S updated MAPREDUCE-6766:
------------------------------
Affects Version/s: 2.7.1
> Concurrent Local Job Failures due to uniqueNumberGenerator = new
> AtomicLong(System.currentTimeMillis())
> -------------------------------------------------------------------------------------------------------
>
> Key: MAPREDUCE-6766
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-6766
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Affects Versions: 2.3.0, 2.7.1
> Environment: Druid 0.8.3
> Reporter: Mark S
>
> I am seeing the following exception when attempting to execute multiple
> Hadoop Local Jobs with Druid.
> {code}
> java.io.IOException: Rename cannot overwrite non empty destination directory
> /tmp/hadoop-username/mapred/local/1472019105135
> {code}
> From a quick look at the Hadoop code base, it seems that the
> uniqueNumberGenerator for the LocalDistributedCacheManager is based on the
> System time, and this appears to cause problems for concurrent jobs.
> {code}
> // Generating unique numbers for FSDownload.
> AtomicLong uniqueNumberGenerator =
> new AtomicLong(System.currentTimeMillis());
> {code}
> I am pretty sure the following line of code is responsible, and this seems to
> exist in latter versions of such as 2.7.1:
