[jira] [Commented] (HADOOP-8036) TestViewFsTrash assumes the user's home directory is 2 levels deep

["Aaron T. Myers (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-8036?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13209676#comment-13209676 ] 

Aaron T. Myers commented on HADOOP-8036:
----------------------------------------

I'm a little surprised you need to call {{tearDown}} explicitly in {{setUp}}. I believe that any method annotated with {{@After}} is guaranteed to run regardless of the failure of the test which it's being run after (unless the JVM exits, but we've got a heap of trouble if that happens.)

> Looks like HADOOP-7974 didn't fix the issue. Still get "Path /var already exists as dir; cannot create link here Stacktrace" when running on jenkins with home dir /var/lib/jenkins.
