>                 Key: ARROW-404
>                 URL: https://issues.apache.org/jira/browse/ARROW-404
>             Project: Apache Arrow
>          Issue Type: Bug
>          Components: Python
>            Reporter: Wes McKinney
>
> Reproducible as follows:
> {code}
> In [3]: con = io.HdfsClient.connect(...)
> In [4]: f = con.open(hdfs_file_path)
> In [5]: con = None
> In [6]: f = None
> {code}
> The attempt to invoke {{CloseFile}} on the internal file handle in {{f}} causes the JVM to segfault. {{f}} should retain a reference to its parent {{con}} so this does not occur
