> 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 http://stackoverflow.com/questions/14602062/java-string-split-removed-empty-values
