--------------------------------

             Summary: Index out of range exception with environment variables 
without values
                 Key: YARN-3768
                 URL: https://issues.apache.org/jira/browse/YARN-3768
             Project: Hadoop YARN
          Issue Type: Bug
          Components: yarn
    Affects Versions: 2.5.0
            Reporter: Joe Ferner


Looking at line 80 of org.apache.hadoop.yarn.util.Apps an index out of range 
exception occurs if an environment variable is encountered without a value.

I believe this occurs because java will not return empty strings from the split 
method. Similar to this
