Subject [jira] [Created] (TAJO-180) Better error messages for StorageManager.listStatus$InvalidInputException
Date Thu, 12 Sep 2013 07:16:53 GMT
Hyunsik Choi created TAJO-180:
---------------------------------

             Summary: Better error messages for StorageManager.listStatus$InvalidInputException
                 Key: TAJO-180
                 URL: https://issues.apache.org/jira/browse/TAJO-180
             Project: Tajo
          Issue Type: Bug
          Components: storage
            Reporter: Hyunsik Choi
            Priority: Minor
             Fix For: 0.2-incubating


StorageManager incurs the following error due to some file name mismatch or other I/O exceptions.
But, the unimplemented InvalidInputException class results in empty error messages. We need
to improve the error message for this exception.

The main goal of this issue is to implement InvalidInputException completely.
