Subject [GitHub] spark pull request: [SPARK-9643] Upgrade pyrolite to 4.9
Date Wed, 12 Aug 2015 23:53:10 GMT
Github user angelini commented on the pull request:

    https://github.com/apache/spark/pull/7950#issuecomment-130485312
  
    For the first part, if there was a flag to say: "Do not verify schema" which would avoid
the following block: https://github.com/apache/spark/blob/master/python/pyspark/sql/context.py#L294-L298
that would be super useful.
    
    We already type check our RDDs, so forcing an extra materialization is unnecessary.
    
    As for the erased timezone, that's too bad. Our frameworks enforces timezones for every
datetime so that might be a bit of a blocker for us. Maybe we could make use of schema metadata
(assuming all datetimes in a column are in the same timezone).
