Mark S created MAPREDUCE-6766:
---------------------------------
Summary: 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
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:
* [Hadoop 2.3.0 -
LocalDistributedCacheManager.java#L96|https://github.com/apache/hadoop/blob/release-2.3.0/hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-common/src/main/java/org/apache/hadoop/mapred/LocalDistributedCacheManager.java#L96]
* [Hadoop 2.7.1 -
LocalDistributedCacheManager.java#L96|https://github.com/apache/hadoop/blob/release-2.7.1/hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-common/src/main/java/org/apache/hadoop/mapred/LocalDistributedCacheManager.java#L96]
