    How/where do we update core-site.xml? Need to update core-site.xml to add the following properties to run a oozie job.

    Proxy group for Hadoop.

    Proxy host for Hadoop.

    The problem we see is that the core-site.xml is being built every time when hadoop starts and as such we don’t know where to put those updates. Also we cannot modify anything on ‘Custom Hadoop Configs’ through Ambari admin as that field is grayed out.

    Here is the command and the error:

    oozie job -config /home/user1/oozie/ -run
    Error: E0902 : E0902: Exception occured: [org.apache.hadoop.ipc.RemoteException: User: oozie is not allowed to impersonate user1]

    Hi Angappan,

    You can change these properties by setting them in both the custom HDFS configs and the custom MapReduce configs. NOTE: to be able to save the changes you’ll need to stop HDFS and MapReduce services completely, make the settings changes and then restart HDFS and MapReduce. Also of note is that in the latest release of Ambari/HDP these settings are available to change in custom Hadoop configs.
