Bootstrap Timeout during cluster start - Azure Data bricks

[bindan]

When I created a cluster on a new deployed Azure data bricks , It’s not starting and giving below message "Bootstrap Timeout" Please try again later, Instance bootstrap Timeout Failure message: Bootstrap script took too long and timeout. please try again later, VM extension code: provisionState/succeede instanceld.

Boostrap timeout happens when the endpoints are missing or if there are any network configuration changes. Please check the UDR settings.

I have run into similar issues before. Make sure DNS is working properly!

If the cluster is up you can verify dns with:

!dig somehostname

Or enable cluster logs and add some debug (routing / dns) statements in start-up script. They are stored on dbfs
