Subject [jira] [Resolved] (HADOOP-8591) TestZKFailoverController tests time out
Date Sat, 06 Oct 2012 01:40:03 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-8591?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Aaron T. Myers resolved HADOOP-8591.

    Resolution: Invalid
      Assignee: Aaron T. Myers

I looked into this today and realized that it was a problem with a particular Jenkins slave.
Whenever a pre-commit test or nightly build was run on hadoop1, it would fail. Whenever it
was run anywhere else, it would pass. When I logged in to hadoop1, I noticed that there were
a bunch of pre-commit processes and even a nightly build that had been running for weeks or
months. After killing these zombie processes, TestZKFailoverController now passes reliably
on hadoop1.
