Date Tue, 14 Jun 2011 01:50:47 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7389?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13048944#comment-13048944

> As mentioned in HADOOP-6671, {{UserGroupInformation.createUserForTesting(...)}} manipulates
static state which can cause test cases which are run after a call to this function to fail.
