Description

If you do a sequential test run of hadoop-aws, you get a failure on ITestS3AMiniYarnCluster, with a message about Kerberos coming from inside job launch.

[ERROR] testWithMiniCluster(org.apache.hadoop.fs.s3a.yarn.ITestS3AMiniYarnCluster)  Time elapsed: 3.438 s  <<< ERROR!
java.io.IOException: Can't get Master Kerberos principal for use as renewer
	at org.apache.hadoop.fs.s3a.yarn.ITestS3AMiniYarnCluster.testWithMiniCluster(ITestS3AMiniYarnCluster.java:117)

Assumption: some state in the single JVM is making this test think it should be using Kerberos.
