-----------------------------------

             Summary: Write to parquet with InMemoryOutputStream
                 Key: ARROW-1067
                 URL: https://issues.apache.org/jira/browse/ARROW-1067
             Project: Apache Arrow
          Issue Type: Bug
          Components: Python
    Affects Versions: 0.4.0
         Environment: Debian 8.5, Anaconda Python 3.6, pyarrow 0.4.0a0
            Reporter: Chase Slater
            Priority: Minor


When I run the following (from the docs) python crashes during the pq.write_table statement.  How would I go about writing a parquet file to a file buffer (e.g. for use with Azure Data Lake)?
{code}
import pyarrow as pa
import pyarrow.parquet as pq
table = pa.Table.from_pandas(df, timestamps_to_ms=True)
with adl.open(my_file_path, 'wb') as f:
    output = pa.InMemoryOutputStream()
    pq.write_table(table, output) # crashes here
    f.write(output.get_result().to_pybytes())
{code}
