Properties to check when changing a server's domain or IP address

[amr_elwadiah]

Question

What properties need to be changed or checked when planning to change an Incorta server domain or IP address.

Answer

Here is a list to check for the hostname change. All are in the CMC portal:

• Metadata database connection string in Details tab
• Zookeeper hostname in Details tab
• Node hostname and IP in the Nodes tab by clicking on the three dots beside the node
• Notebook hostname and IP in the Nodes tab by clicking on the three dots beside the node
• Spark master URL in Server Configurations
• Email in Server Configurations
• Data Agent in Server Configurations
• Under the tenant’s configurations:
  • Provider configurations under Security, if SSO is used
  • Email
  • External Visualization Tools

For Spark:

Check the hostnames defined in these configuration files:

• <spark_home>/conf/spark-defaults.conf
• <spark_home>/conf/spark-env.sh

If Spark is on a separate node and its hostname is not changed, then you can do not need to check its configuration files.

Steps

Follow these steps to proceed:

1. Stop all services
2. Update the hostname
3. Start the CMC only, then review the list above and update as required
4. Start the rest of the services in this order:
   1. Node
   2. Spark
   3. Loader
   4. Analytics
