dataproc/Check Cluster Network Connectivity

Verify that the nodes in the cluster can communicate with each other.

Product: Cloud Dataproc
Step Type: AUTOMATED STEP

Description

The Compute Engine Virtual Machine instances (VMs) in a Dataproc cluster must be able to communicate with each other using ICMP, TCP (all ports), and UDP (all ports) protocols.

Failure Reason

The network communication among nodes in cluster {cluster_name} is blocked.

Failure Remediation

Create a firewall rule that meets Dataproc connectivity requirements[1] and apply it to the cluster’s VPC network. Review the documentation[2] for more details.

Success Reason

The network communication among nodes in cluster {cluster_name} is working.

Uncertain Reason

The cluster has not been found, it may have been deleted. Skipping the connectivity test.

Uncertain Remediation

Verify that Dataproc connectivity requirements[1] are satisfied. References: [1] https://cloud.google.com/dataproc/docs/concepts/configuring-clusters/network#dataproc_connectivity_requirements
