Jim Pivarski commented on PARQUET-1199:
---------------------------------------
I happen to have appropriate test files. The following is correct output.
[https://github.com/diana-hep/oamap/blob/master/tests/samples/record-primitives.parquet

The following is correct output from pyarrow 0.8.0.
{{>>> import pyarrow.parquet}}
{{>>> f1 = pyarrow.parquet.read_table("record-primitives.parquet",
columns=["u1", "u4"])}}
{{>>> f2 = pyarrow.parquet.read_table("nullable-record-primitives.parquet",
columns=["u1", "u4"])}}
{{>>> f1[0]}}
{{<pyarrow.lib.Column object at 0x7ec13d01ea50>}}
{{chunk 0: <pyarrow.lib.BooleanArray object at 0x7ec13d09a3c0>}}
