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

             Summary: libhdfs doesn't return correct error codes in most cases
                 Key: HDFS-4997
                 URL: https://issues.apache.org/jira/browse/HDFS-4997
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: libhdfs
            Reporter: Colin Patrick McCabe
            Assignee: Colin Patrick McCabe


libhdfs has some code to translate Java exceptions into C error codes.  Unfortunately, the exceptions are returned to us in "dotted" format, but the code is expecting them to be in "slash-separated" format.  This results in most exceptions just leading to a generic error code.

We should fix this and add a unit test to ensure this continues to work.
