How to configure:

  1. SCP over configurations from your Standby NameNode into /usr/local/nn-analytics/config
  2. Modify your hdfs-site.xml and ensure that Kerberos information is valid. NNA requires a keytab with nn user principal if you are using Kerberos. Just like a real NameNode.
  3. Modify and set up LDAP authentication, SSL, and authorization.
  4. Ensure that file is only read-able by hdfs and root users: chown hdfs: && chmod 400
