Wes McKinney commented on PARQUET-1169:
---------------------------------------
You aren't checking the status codes for some of the Arrow functions. Try using
a macro similar to {{ABORT_NOT_OK}} (but prints the error message to
{{std::cout}}) to see the error message:

> Segment fault when using NextBatch of parquet::arrow::ColumnReader in
