Description

In our internal Jenkins build, I saw failure in TestZKSecretWatcher:

java.lang.ArrayIndexOutOfBoundsException: 2
	at org.apache.hadoop.hbase.security.token.TestZKSecretWatcher.setupBeforeClass(TestZKSecretWatcher.java:87)
	at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
	at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)
	at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)

This was due to i being 1, resulting in index of 2 being used in the following statement:

          KEY_SLAVE = tmp[ i+1 % 2 ];
