Description

When Oozie is used with Hadoop trunk (specifically, a Hadoop that includes HADOOP-8855) the Oozie CLI will throw a Null Pointer Exception if Oozie is using simple authentication, the .oozie-auth-token doesn't already exist, and the user doesn't supply -auth SIMPLE. Once the user supplies -auth SIMPLE, the .oozie-auth-token file is written and -auth SIMPLE is no longer needed for subsequent commands.

The NPE looks something like this:

$ oozie admin -version
java.lang.NullPointerException
	at java.io.Writer.write(Writer.java:140)
	at org.apache.oozie.client.AuthOozieClient.writeAuthToken(AuthOozieClient.java:182)
