    Description

      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.

      java.lang.ArrayIndexOutOfBoundsException: 1
	at org.apache.hadoop.yarn.util.Apps.setEnvFromInputString(Apps.java:80)

      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
