ERROR WHILE CREATING CLUTER IN COMMUNITY VERSION

[_raman_]

From past two hours i am trying to create a cluster but it is getting failed after trying of 15-20 minutes.

the red sign is coming after the cluster name which says that : Bootstrap Timeout:
Node daemon ping timeout in 780000 ms for instance i-05ff43bc1d12412b5 @ 10.172.216.96. Please check network connectivity between the data plane and the control plane.

Hi @_raman_, I understand that you’re facing issues while creating a cluster, and you’re encountering a Bootstrap Timeout error with the message:

Node daemon ping timeout in 780000 ms for instance i-05ff43bc1d12412b5 @ 10.172.216.96. Please check network connectivity between the data plane and the control plane.

This error typically occurs when there’s a problem with communication between the data plane (where your cluster nodes reside) and the control plane (where the cluster management services operate).

Let’s troubleshoot this issue:

1. Network Connectivity:

   • First, ensure that there’s proper network connectivity between the data plane and the control plane. Check if there are any network issues, firewalls, or security groups blocking communication.
   • Verify that the security groups associated with your instances allow the necessary traffic (such as SSH, HTTP, and HTTPS) between the nodes and the control plane.

2. EC2 Instance Logs:

   • Review the EC2 instance logs in AWS for more details about the error. Look for any specific messages related to connectivity issues or timeouts.
   • Check if there are any issues related to the instance itself (such as resource constraints or misconfigurations).

3. Subnet Route Table and Security Groups:

   • Examine the subnet route table configuration. Ensure that the route table allows traffic between the data plane and the control plane.
   • Verify that the security groups associated with your instances are correctly configured. Make sure no changes have been inadvertently made.

4. Cluster Initialization:

   • Sometimes, clusters fail to initialize due to transient issues. Retry creating the cluster after some time.
   • If the problem persists, consider checking the status of Databricks services. You can find the status information on the Databricks status page (under AWS).

I hope this helps resolve the issue! If you have any other questions or need additional guidance, feel free to ask. 🚀
