Description

I am unable to read a parquet file that was made after converting a csv to a parquet file using pyarrow. Following is the error 

ArrowIOError Traceback (most recent call last) in () ~/anaconda3/lib/python3.6/site-packages/pyarrow/parquet.py in read_table(source, columns, nthreads, metadata, use_pandas_metadata) 937 return fs.read_parquet(source, columns=columns, metadata=metadata) 938 --> 939 pf = ParquetFile(source, metadata=metadata) 940 return pf.read(columns=columns, nthreads=nthreads, 941 use_pandas_metadata=use_pandas_metadata) ~/anaconda3/lib/python3.6/site-packages/pyarrow/parquet.py in __init__(self, source, metadata, common_metadata) 62 self.reader = ParquetReader() 63 source = _ensure_file(source) ---> 64 self.reader.open(source, metadata=metadata) 65 self.common_metadata = common_metadata 66 self._nested_paths_by_prefix = self._build_nested_paths() _parquet.pyx in pyarrow._parquet.ParquetReader.open() error.pxi in pyarrow.lib.check_status() ArrowIOError: Invalid parquet file. Corrupt footer.

 

I was able to read and write parquet file earlier (about a few days ago) and how its stopped working 

**Environment**: Linux x86

Research direction

Reproduce the report on Linux x86 with Anaconda Python 3.6 and pyarrow 0.9.0 by reading a Parquet file created from CSV, then inspect the reported ArrowIOError about a corrupt footer. The issue provides no repository file or test; determine whether the conversion output or the reader is responsible before defining a fix and regression test.
