When attempting to edit the schedule cron expression on one of our jobs we receive the following error message:
Cluster validation error: Validation failed for spark_conf, spark.databricks.acl.dfAclsEnabled must be false (is "true")
The spark.databricks.acl.dfAclsEnabled property on the jobs cluster is currently set to false. Therefore the error message if misleading and there must be some other reason the update is failing.
Any change to the schedule cron expression fails with this error. E.g. changing the cron expression from 35 0 1/3 * * ? to 34 0 1/3 * * ?.
Update
We get the same error even when creating a new job. So this seems to be a major and more widespread issue.
