HA Ambari server

  • #34582

    I’m wondering what happens if my Ambari server crashes, drives fail, etc. Can you have dual Ambari servers? What is the best way to make sure that everything is fully HA?

    Hello Andy,

    The primary thing is to make sure your Ambari DB is backed-up. These instructions discuss backing-up + restoring the database, and installing a replacement Ambari Server (and re-pointing your Ambari Agents if necessary).

    One more note on the database, you also have the option of running Oracle, instead of PostgreSQL, if that helps with your database management tasks.

    Thanks,

    Thanks! A followup question – does that mean that the Ambari server should be nothing but the Ambari server? Does it complicate things if the Ambari server is also the HBase Master and a NameNode?
