Adding Components
Last updated: 2024-10-30 11:06:53
After the cluster is created, you can add other components supported by the selected product version through the Add Component operation. This document introduces how to add components through the console.
Note
Note Adding components only supports selecting components from the current EMR product version.

Directions

1. Log in to the EMR on TKE Console and click the Cluster ID/Name in the cluster list to enter the cluster details page.
2. Select Cluster Information > Basic Configuration, and then select Add Components from the service architecture diagram to add components that have not been installed in the cluster.
3. When the cluster lacks a metadatabase, a CloudDB instance storage unit should be purchased to serve as the metadata storage when you install the Hue or Ranger components.
4. The Hive component metadata storage provides two storage methods: the first is the default cluster option, where metadata is stored in MetaDB; the second is an association option, where the metadata can be stored in an associated EMR-MetaDB or an associated self-built MySQL database, and it will not be terminated when the cluster is terminated.
5. Whether to purchase MetaDB is consistent with the configuration during the new cluster purchase, and the Hive metastore selection is also consistent with the configuration during the new cluster purchase.
6. After the components are selected, click Create to proceed.
