Bootstrap Timeout during cluster start

[LearningDatabri]

sometimes while starting a cluster I am facing bootstrap timeout error, what is the reason? when I try the next time it starts the cluster.

In which region your workspace is deployed? Also which is the cloud provider? We recently applied a fix to resolve this bootstrap error.

Hello, we have started to see this issue in Canada Central, on Azure, mostly around 6:15am.

By adding this property on cluster level, it started working.

spark.sql.legacy.timeParserPolicy to LEGACY

The bootstrap timeout error happens when the cluster setup process takes too long, usually due to network delays, resource allocation issues, or communication problems with the cloud provider. It’s likely a temporary glitch, which is why retrying works the next time. If it keeps happening, check your cluster configurations or contact support for troubleshooting.
