Subject [jira] [Commented] (HAMA-848) Refactor YARN module for hadoop 2.x stable version
Date Fri, 13 Feb 2015 08:02:14 GMT

    [ https://issues.apache.org/jira/browse/HAMA-848?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14319722#comment-14319722
] 

Edward J. Yoon commented on HAMA-848:
-------------------------------------

As described in method comment, 

{code}
  /**
   * Writes the current configuration to a given path to reflect changes. For
   * example the sync server address is put after the file has been written.
   */
  private static void rewriteSubmitConfiguration(String path, Configuration conf)
      throws IOException {
{code}

After startSyncServer() and startRPCServers() are called, sync and task report servers' address
were newly added. Therefore, we need to overwrite config file to readjust.

> Current yarn-module was implemented based on Hadoop 0.23.1 version. You'll need to use
the Hama RPC instead of Hadoop RPC.
