Subject [jira] [Updated] (HBASE-9664) ArrayIndexOutOfBoundsException may be thrown in TestZKSecretWatcher
Date Thu, 26 Sep 2013 19:07:06 GMT

     [ https://issues.apache.org/jira/browse/HBASE-9664?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Ted Yu updated HBASE-9664:
--------------------------

    Description: 
In our internal Jenkins build, I saw failure in TestZKSecretWatcher:
{code}
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)
{code}
This was due to i being 1, resulting in index of 2 being used in the following statement:
{code}
          KEY_SLAVE = tmp[ i+1 % 2 ];
{code}

See http://docs.oracle.com/javase/tutorial/java/nutsandbolts/operators.html
