Spark UI simulator is not available online

Bartek — Wed, 14 Dec 2022 22:07:11 GMT

About 2 weeks ago I started course on "Optimizing Apache Spark on Databricks" from official Databricks academy. It is heavily based on Spark UI simulator experiments that were available here: https://www.databricks.training/spark-ui-simulator and for me it was just great source.

Unfortunately, they were available, that's the issue - unexpectedly the page fails to load and it is hard to continue course without access to analyzed experiments.

Does anyone know what happened to this Spark UI Simulator?

Hi @Bartosz Maciejewski ,

Can you try loading the website without https and instead just http like http://www.databricks.training/spark-ui-simulator/ ?

Hi @Landan George,

thanks, yes, it works with this protocol.

I was not aware that the certificate will be dropped - but for me the most important that the resource is available.

Cheers

Bartek

Hi @LandanG

The link is still not working. Any idea when it will be live again?
