Project: Hadoop YARN
Issue Type: Bug

The apps API works fine and give all applications, including Mapreduce and Tez
http://<host>:8188/ws/v1/applicationhistory/apps
But when queried with application types with these APIs, it fails with
NullpointerException.
http://<host>:8188/ws/v1/applicationhistory/apps?applicationTypes=TEZ
http://<host>:8188/ws/v1/applicationhistory/apps?applicationTypes=MAPREDUCE
<RemoteException><exception>NullPointerException</exception><javaClassName>java.lang.NullPointerException</javaClassName></RemoteException>
Blocked on this issue as we are not able to run analytics on the tez job
counters on the prod jobs.
