external jars in .20

[Lance Riedel <la...@dotspots.com>]

We are trying to upgrade to .20 from 19.1 due to several issues we are
having.  Now are jobs are failing with class not found exceptions.

I am very confused about the final state for using external jars in .20.

-libjars no long works

placing all dependent jars in the jar /lib directory doesn't work

See:
https://issues.apache.org/jira/browse/HADOOP-4612

where the code:

//adding libjars to the classpath
    Configuration conf = JobClient.getCommandLineConfig();
    URL[] libJars = GenericOptionsParser.getLibJars(conf);
    if(libJars!=null) {
      for(URL url : libJars){
        classPath.add(url);
      }
    }

Has been removed, and says it is no longer needed.. Where are the docs
for this change?


Thanks,
Lance

Hi Lance,

Where are you passing the -libjars parameter? It is now GenericOption. 
It is no more a parameter for jar command.

Thanks
