> Key: ARROW-6248
> URL: https://issues.apache.org/jira/browse/ARROW-6248
> Project: Apache Arrow
> Issue Type: Improvement
> Components: Python
> Affects Versions: 0.14.1
> Reporter: Alexander Schepanovski
> Priority: Minor
> Fix For: 5.0.0
>
>
> When file is absent pyarrow throwsÂ
> {code:python}
> ArrowIOError('HDFS file does not exist: ...')
> {code}
> which inherits from {{IOError}} and {{pyarrow.lib.ArrowException}}, it would be better if that was {{FileNotFoundError}} a subclass of {{IOError}} for this particular purpose. Also, {{.errno}} property is empty (should be 2) so one needs to match by error message to check for particular error.
> *P.S.* There is no {{FileNotFoundError}} in Python 2, but there is {{.errno}} property there.
