Description

After 39 runs the TestAMRMClient test, I encountered:

java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
       	at java.util.ArrayList.rangeCheck(ArrayList.java:635)
       	at java.util.ArrayList.get(ArrayList.java:411)
       	at org.apache.hadoop.yarn.client.api.impl.TestAMRMClient.setup(TestAMRMClient.java:144)

I see it shows up occasionally in the error emails as well.
