Description
I'm receiving the following traceback:
>>> sc.textFile('test.txt').repartition(10).collect() Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/local/Cellar/apache-spark/2.1.0/libexec/python/pyspark/rdd.py", line 810, in collect return list(_load_from_socket(port, self._jrdd_deserializer)) File "/usr/local/Cellar/apache-spark/2.1.0/libexec/python/pyspark/rdd.py", line 140, in _load_from_socket for item in serializer.load_stream(rf): File "/usr/local/Cellar/apache-spark/2.1.0/libexec/python/pyspark/serializers.py", line 539, in load_stream yield self.loads(stream) File "/usr/local/Cellar/apache-spark/2.1.0/libexec/python/pyspark/serializers.py", line 534, in loads return s.decode("utf-8") if self.use_unicode else s File "/Users/brianbruggeman/.envs/dg/lib/python2.7/encodings/utf_8.py", line 16, in decode return codecs.utf_8_decode(input, errors, True) UnicodeDecodeError: 'utf8' codec can't decode byte 0x80 in position 0: invalid start byte
I created a textfile (text.txt) with standard linux newlines:
a b d e f g h i j k l
I think ran pyspark:

This really looks like a bug in the `serializers.py` code.
