including multiple user jar files into class path is not working
----------------------------------------------------------------
Key: MAPREDUCE-4018
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4018
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: distributed-cache
Affects Versions: 1.0.0
Environment: submit job from Windows to Linux
Reporter: Weili Shao
I am trying to submit a job which is using some third-party libs. I tried both
-libjars and DistributedCache directly. Both are not working until I merge all
jar files into one big jar file.
The way I am using -libjars: -libjars <path>/file1.jar,<path>/file2.jar,....
The way I am using DistributedCache:
FileSystem hdfs = FileSystem.get(new URI("hdfs://remotehost:9000"),
conf);
DistributedCache.addArchiveToClassPath(new Path("<path>/file1.jar"),
conf, hdfs);
DistributedCache.addArchiveToClassPath(new Path("<path>/file2.jar"),
conf, hdfs);
The error messages I observed would have been changing if I have different
number of jars in the path. It looks like only one of the jars would be in the
classpath for any submission. So I decided to merge all jar files into one big
jar file and try again. Now it works. It looks like there is a bug to include
multiple jar files into classpath.
