             Summary: Allow Configuration to be persisted given path to file
                 Key: HADOOP-14076
                 URL: https://issues.apache.org/jira/browse/HADOOP-14076
             Project: Hadoop Common
          Issue Type: Improvement
            Reporter: Ted Yu


Currently Configuration has the following methods for persistence:
{code}
  public void writeXml(OutputStream out) throws IOException {

  public void writeXml(Writer out) throws IOException {
{code}
Adding API for persisting to file given path would be useful:
{code}
  public void writeXml(String path) throws IOException {
{code}

Background: I recently worked on exporting Configuration to a file using JNI.
Without the proposed API, I resorted to some trick such as the following:
