How Do I Improve the Resource Utilization of Core Nodes in a Cluster?
- Go to the Yarn service configuration page.
- For MRS 1.8.10 or earlier clusters:
Log in to MRS Manager by referring to Accessing MRS Manager. Choose Services > Yarn > Service Configuration, and select All from the Basic drop-down list.
- For MRS 1.8.10 or later and MRS 2.x, click the cluster name. On the cluster details page that is displayed, click the Components tab and choose Yarn. Click the Service Configuration and select All from the Basic drop-down list.
If the Components tab is unavailable, complete IAM user synchronization first. (On the Dashboard page, click Synchronize on the right side of IAM User Sync to synchronize IAM users.)
- For MRS cluster version 3.x or later:
Log in to FusionInsight Manager. Choose Cluster > Name of the desired cluster > Services > Yarn > Configurations > All Configurations.
- For MRS 1.8.10 or earlier clusters:
- Search for yarn.nodemanager.resource.memory-mb, and increase the value based on the actual memory of the cluster nodes.
- Save the change and restart the affected services or instances.
