No support to set dfs.support.append in Ambari install?

  • #30296

    Just finished an Ambari install of HDP 1.3

    While running our own HDFS check app, see that Append support is disabled:
    Exception in thread “main” org.apache.hadoop.ipc.RemoteException: java.io.IOException: Append is not supported. Please see the dfs.support.append configuration parameter
    at org.apache.hadoop.hdfs.server.namenode.FSNamesystem.appendFile(FSNamesystem.java:1842)

    I checked he Ambari HDFS configuration page and there is no dfs.support.append setting.

    I then tried to add a custom property to hdfs-site.xml but got this error:
    This property is already defined

    Any suggestions?

    Bob this looks like a bug…
    It accepting default settings, which is in the main jar file…
    The only workaround if not use Ambari for managing cluster for now.
    put needed property to core-site.xml and start/stop HDFS manually….

    Sorry for inconvenience…

    Thank you!
