Major Description
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.
Full Stack trace from the test failure:
