Subject [jira] Commented: (HDFS-525) ListPathsServlet.java uses static SimpleDateFormat that has threading issues
Date Mon, 10 Aug 2009 21:06:14 GMT

    [ https://issues.apache.org/jira/browse/HDFS-525?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12741551#action_12741551

Suresh Srinivas commented on HDFS-525:

It is important to have unit test to ensure correct functionality. The only reason why I left
the negative test case is to justify 30 seconds wait time for which we run multi threaded
access. The first negative test that proves there is a threading issue fails in under a second.
This should not add to the time of the test.

BTW as Gary indicated, my intention was not to include this in under 10 minute tests.
