    [ https://issues.apache.org/jira/browse/HAMA-128?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12674428#action_12674428 ] 

Samuel Guo commented on HAMA-128:
---------------------------------

When job failed, the result matrix will be closed and a non-aliased matrix will be removed during closing.
so we don't need this jira. I will close it.

the code in JobManager as below has done this function.

  public static void execute(JobConf jobConf, Matrix result) throws IOException {
    try {
      JobClient.runJob(jobConf);
      // TODO : Thinking about more efficient method.
      int rows = result.getColumn(0).size();
      int columns = result.getRow(0).size();
      result.setDimension(rows, columns);
    } catch (IOException e) {
      result.close(); // <----------------here, the output will be deleted.
      throw new IOException(e);
    }
  }
