             Summary: Odd failures w/ "UnknownTimeZoneError: 'US/Pacific-New'"
                 Key: SPARK-27389
                 URL: https://issues.apache.org/jira/browse/SPARK-27389
             Project: Spark
          Issue Type: Task
          Components: jenkins
    Affects Versions: 3.0.0
            Reporter: Imran Rashid
            Assignee: shane knapp


I've seen a few odd PR build failures w/ an error in pyspark tests about "UnknownTimeZoneError: 'US/Pacific-New'".  eg. https://amplab.cs.berkeley.edu/jenkins/job/NewSparkPullRequestBuilder/4688/consoleFull

A bit of searching tells me that US/Pacific-New probably isn't really supposed to be a timezone at all: https://mm.icann.org/pipermail/tz/2009-February/015448.html

I'm guessing that this is from some misconfiguration of jenkins.  that said, I can't figure out what is wrong.  There does seem to be a timezone entry for US/Pacific-New in {{/usr/share/zoneinfo/US/Pacific-New}} -- but it seems to be there on every amp-jenkins-worker, so I dunno what that alone would cause this failure sometime.

[~shaneknapp] I am tentatively calling this a "jenkins" issue, but I might be totally wrong here and it is really a pyspark problem.
