Adding Druid to a cluster

Configure the Druid installation

Using Ambari facilitates configuring Druid by presenting parameters in a graphical user interface.

This task covers how to configure basic settings. You can access other settings on the Advanced tab.

Ambari has Stack Advisor, which is configuration wizard. Stack Advisor populates many configuration settings based on the your previously entered settings and your environment. Although Stack Advisor provides many default settings for Druid nodes and other related entities in the cluster, you might need to manually tune the configuration parameter settings.

  1. In Customize Services, select Metadata storage type > Druid.
  2. From the drop-down, notice the database types that appear, and then select Derby for a quick non-production installation, MySQL, or Postgres database.
  3. In Metadata storage password, enter the a password.
    If you selected MySQL or Postgres, setup your metadata storage database, and other settings on the Advanced tab.
  4. Review the documentation to determine if you need to change any default settings and how other manual settings operate.
