I am running this Delta Live Tables PoC from databricks-industry-solutions/industry-solutions-blueprints

https://github.com/databricks-industry-solutions/pos-dlt

I have Standard_DS4_v2 with 28GB and 8 cores x 2 workers - so a total of 16 cores. This is more than what Databricks recommends for this PoC (Standard_DS3_v2 with 4 cores x 2 workers).

There are 5 notebooks in the PoC. I have run Notebook 1 and 2 individually without errors.

However when I execute the entire PoC from the RUNME.py orchestrator, it fails on Notebook 2 with this error:

Unexpected failure while waiting for the cluster (0608-160733-23lp3pel) to be ready: Cluster 0608-160733-23lp3pel is in unexpected state Terminated: AZURE_QUOTA_EXCEEDED_EXCEPTION (CLIENT_ERROR): azure_error_code:QuotaExceeded, azure_error_message: Operation could not be completed as it results in exceeding approved standardDSv2Family Cores quota. Additional details - Deployment Model: Resource Manager, Location: eastus, Current Limit: 32, Current Usage: 24, Additional Required: 16, (Minimum) New Limit Required: 40. Submit a request for Quota increase at https://aka.ms/ProdportalCRP/#blade/Microsoft_Azure_Capacity/UsageAndQuota.ReactView/Parameters/%7B%...<......long url parameters list>...................

I have tried increasing the quota, but same error, so I dont think it is the Quota increase. There seems always a need for more and more vCPUs. This is the Inner exepction:

Any clues? Any of these reasons?
