[jira] [Updated] (ARROW-7282) [Python] IOError subclassing

["Scott Gigante (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/ARROW-7282?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Scott Gigante updated ARROW-7282:
---------------------------------
    Description: 
I get the following error when trying to open a file that does not exist.

 

```
 pyarrow.lib.ArrowIOError: Failed to open local file 'filename', error: No such file or directory

```

 

In my opinion, this particular error should also subclass from Python FileNotFoundError. It currently only inherits from IOError (which is a superclass of FileNotFoundError).

  was:

```

```

 

Two issues here:
 # pyarrow.lib.ArrowIOError doesn't inherit from Python IOError
 # This particular error should also subclass from Python FileNotFoundError
