Subject [jira] [Commented] (HADOOP-10394) TestAuthenticationFilter is flaky
Date Sat, 08 Mar 2014 01:15:43 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10394?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13924621#comment-13924621

Arpit Agarwal commented on HADOOP-10394:
----------------------------------------

I am not familiar with this the code that is being tested but from a quick look it appears
safe to increase the fudge factor up to a couple of seconds without compromising the correctness
of the test case.
