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

             Summary: [C++] Improve error message when opening OS file fails
                 Key: ARROW-1121
                 URL: https://issues.apache.org/jira/browse/ARROW-1121
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
    Affects Versions: 0.4.1
            Reporter: Wes McKinney


The error in CheckOpenResult 
https://github.com/apache/arrow/blob/master/cpp/src/arrow/io/file.cc#L130 could 
be more clear to indicate that it's trying to open a local on-disk file. If a 
user tries passing a URI for some other kind of file system then this may not 
be as obvious.
