    Hi Jakub,

    Actually Ambari support Namenode HA pretty well in version 1.4.1 or later versions. After we use ambari to enable the Namenode HA. every other components are configured by Ambari automatically. Please note I assume you are achieving the natural Hadoop HA, not VMware HA or Redhat HA.

    If you want to configure it manually, here is some basic steps you can start with:
    1. Shut Down the HBase Cluster
    2. Specified the hbase.rootdir property in hbase-site.xml to the same value as dfs.nameservices in hdfs-site.xml
    3. Start Hbase cluster.

    Hope this helps.

    Thanks,
    Kenny

    Hi Kenny,
    we are not using an abari at all and in HDP 2.0 system admin guide it is even required to disable ambari to achive HA, if I understood correctly.

    Hi Jakub,

    Are you using Ambari to install and mange a HDP cluster?
    If yes, what version of HDP and Ambari you are using?

    Thanks,
