Subject [jira] [Commented] (MAPREDUCE-4798) TestJobHistoryServer fails some times with 'java.lang.AssertionError: Address already in use'
Date Fri, 16 Nov 2012 03:24:12 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4798?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13498567#comment-13498567
] 

Eric Yang commented on MAPREDUCE-4798:
--------------------------------------

Could we indent the if block properly?  In addition, could we do more to check the URL redirect
method in a while loop with a maximum of 4 retries?  We can add synthetic logic to pause 1,
2, 3, and 4 seconds upon each retry.  Hence, the worst case would be delayed by 10 seconds,
but it can recover earlier than 10 seconds in most cases.  This could reduce the amount of
time required to execute this test case.
