Jobs failing with repl error

[ossinova]

Recently my Databricks jobs have failed with the error message:

Failure starting repl. Try detaching and re-attaching the notebook.
 
java.lang.Exception: Python repl did not start in 30 seconds seconds.
	at com.databricks.backend.daemon.driver.IpykernelUtils$.startIpyKernel(JupyterDriverLocal.scala:1469)
	at com.databricks.backend.daemon.driver.JupyterDriverLocal.startPython(JupyterDriverLocal.scala:1084)
	at com.databricks.backend.daemon.driver.JupyterDriverLocal.<init>(JupyterDriverLocal.scala:624)

	at com.databricks.backend.daemon.driver.DriverWrapper.run(DriverWrapper.scala:231)
	at java.lang.Thread.run(Thread.java:750)

The job is attached to a pool using Spot Pricing.

What is the best procedure to avoid this? Adding retry?

Yes, you can use re-try if still it's not resolve raise a support ticket to databricks
