             Summary: pyspark: UTF-8 not written correctly (as CSV) when locale is not UTF-8
                 Key: SPARK-18571
                 URL: https://issues.apache.org/jira/browse/SPARK-18571
             Project: Spark
          Issue Type: Bug
          Components: Input/Output
    Affects Versions: 2.0.2
            Reporter: Adrian Bridgett


Sample code attached, code run with hadoop 2.7.3

If I run this with --master='local[*]' and LANG=en_US.UTF-8, then in _another_ terminal (which has LANG=en_US.UTF-8 set) cat the file, I see the Pi character I expect.

Back to the first terminal, set LANG=C (or unset it) and rerun, then check the output in the other terminal (still set to en_US.UTF-8) and it's corrupted.

I actually noticed this as when I run it with our normal mesos scheduler, the data is corrupted (those boxes do have LANG=en_US.UTF-8 but perhaps it's not being picked up).

I don't remember needing to do this on Spark-1.6.1 (hadoop-2.7.1).

Expected characters: 0x80cf
Received: 0xbfef efbd bdbf
