["Linden Hillenbrand (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SQOOP-743?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13580696#comment-13580696 ] 

Linden Hillenbrand commented on SQOOP-743:
------------------------------------------

Checked each error in MapreduceExecutionError.java and kept ones referenced in the code base and cleaned up the ones that were not being used.

The ones I was able to remove are the following:

  /** Error occurs during job execution. */
  MAPRED_EXEC_0008("Error occurs during job execution"),

  /** The system was unable to load the specified class. */
  MAPRED_EXEC_0009("Unable to load the specified class"),

  /** The parameter already exists in the context */
  MAPRED_EXEC_0011("The parameter already exists in the context"),

  /** Cannot read from the data reader */
  MAPRED_EXEC_0014("Cannot read to the data reader"),

  /** Unable to write data due to interrupt */
  MAPRED_EXEC_0015("Unable to write data due to interrupt"),

  /** Unable to read data due to interrupt */
  MAPRED_EXEC_0016("Unable to read data due to interrupt"),

  /** The required option has not been set yet */
  MAPRED_EXEC_0020("The required option has not been set yet"),

Ran all tests and passed successfully, will post patch here and on RB.

> I've noticed that we have plenty of unused error codes in MapreduceExecutionError, would be great to check why they are not used and remove them if they are really not needed.
