             Summary: Parquet AVRO tests fail

{code}

I see two classes of problems:
# The json with byte arrays appear different.
# Some tests compare the 'toString' of a ByteBuffer. Now for two ByteBuffers that both contain the SAME bytes these tests fail simply because the position field of the ByteBuffer is different. I think these should compare the contents of the ByteBuffer instead.
