             Summary: [Python] Improved error messages when user erroneously uses a non-local resource URI to open a file
                 Key: ARROW-5205
                 URL: https://issues.apache.org/jira/browse/ARROW-5205
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Python
            Reporter: Wes McKinney


In a number of places if a string filepath is passed, it is assumed to be a local file. Since we are developing better support for file URIs, we may be able to detect that the user has passed an unsupported URI (e.g. something starting with "s3:" or "hdfs:") and return a better error message than "local file not found"
