Troubleshoot resource creation failures in Azure HDInsight

  • Article

This article describes troubleshooting steps and possible resolutions for issues when interacting with Azure HDInsight.

Error: The deployment would exceed the quota of '800'

Azure has a quota limit of 800 deployments per resource group. Different quotas are applied per resource group, subscription, account, or other scopes. For example, your subscription may be configured to limit the number of cores for a region. Trying to deploy a virtual machine with more cores than permitted results in error message stating the quota was exceeded.

To resolve this issue, delete the deployments that are no longer needed by using the Azure portal, CLI, or PowerShell.

For more information, see Resolve errors for resource quotas.

Error: The maximum node exceeded the available cores in this region
