Hello, friendly reminder for you. The scm_prepare_database.sh script is used to create and configure a database for the Cloudera Manager Server. It can create the Cloudera Manager Server database configuration file, check the connection between the Cloudera Manager Server and the database, and then after a successful connection, generate and populate necessary tables in the /etc/cloudera-scm-server/db.properties file. That is why multiple database tables are not created until a successful connection takes place. This ensures the database is set up and ready for use by Cloudera Manager. ... View more

Hello Copying a parcel to a node and adding the node to the cluster does not mean Cloudera Manager will recognize that the parcel is already present and skip distribution. Cloudera Manager manages parcel distribution through its centralized management system. When a node is added to the cluster, Cloudera Manager will handle the parcel distribution process according to its internal procedures, ensuring that the correct and complete parcel metadata and components are properly configured and unpacked on the node. This process ensures consistency and reliability in the cluster configuration. Therefore, even if a parcel is manually copied to a node, Cloudera Manager is likely to still perform its distribution process for verification and consistency purposes. Copying the parcels to the nodes before adding them to the cluster is not the proper or suggested way to do it, therefore not supported. The recommended method would be to distribute the parcels by using the Wizard as usual as Cloudera supports the parcel distribution through the UI only. I hope this helps. ... View more

Friendly reminder for you. The recommendation is to use the hostname instead of the IP address for the server_host entry in the /etc/cloudera-scm-agent/config.ini file. This allows more flexibility with DNS resolution and potential IP address changes. ... View more
