Add an HDFS namenode directory

  • #15988

    Hi !

    I would like to add another namenode directory to my current HDFS config via Ambari. But, even if I stop both HDFS and MAP&REDUCE, the corresponding field is still locked and I am not able to modify it.

    Is it possible in Ambari 1.2.1, or is there an alternative way to do that ? I see that you’re using an HTTP POST when configuration is changed, with a JSON object which re-send all the new configuration. Do you confirm this can be a way of doing it manually ? Are there any reasons for some fields to be locked, even if the service is stopped ?

    Many thanks for your help and for that great Hadoop distrib,
