[jira] [Created] (HADOOP-13776) remove redundant classpath entries in RunJar

Sangjin Lee created HADOOP-13776:
------------------------------------

             Summary: remove redundant classpath entries in RunJar
                 Key: HADOOP-13776
                 URL: https://issues.apache.org/jira/browse/HADOOP-13776
             Project: Hadoop Common
          Issue Type: Bug
          Components: util
            Reporter: Sangjin Lee
            Assignee: Sangjin Lee


Today when you run a "hadoop jar" command, the content of the jar gets added to the classpath twice, once in the jar form, and again in an unpacked form.

We should include the content of the jar to the classpath only once. We should keep the jar in the classpath (to support {{setJarByClass}} and other useful use cases) but remove the root of the unpacked directory.
