Delta Live Tables stops in PROVISIONING_PIPELINE_RESOURCES state

Question

Delta Live Tables stops in PROVISIONING_PIPELINE_RESOURCES state

Closed this issue 10 months ago · 7 comments

Whilst running the rag_chatbot demo (01-Data-Preparation-and-Index), I am seeing an error with the Delta Live Tables pipeline.

In the Create the Self-managed vector search using our endpoint cell, the log shows that it is currently provisioning pipeline resources. However, it eventually fails.

Here is the log from the cell:

Waiting for index to be ready, this can take a few min... {'detailed_state': 'PROVISIONING_PIPELINE_RESOURCES', 'message': 'Index is currently pending setup of pipeline resources. Check latest status in Delta Live Tables: https://dbc-73e12b42-36d2.cloud.databricks.com#joblist/pipelines/18350724-c5a7-4af0-9d11-d5b184b74641/updates/f1a8374d-1edf-4f7a-a6a3-b7aff0831d5e', 'indexed_row_count': 0, 'provisioning_status': {}, 'ready': False, 'index_url': 'dbc-73e12b42-36d2.cloud.databricks.com/api/2.0/vector-search/endpoints/dbdemos_vs_endpoint/indexes/main.rag_chatbot.databricks_documentation_vs_index'} - pipeline url:dbc-73e12b42-36d2.cloud.databricks.com/api/2.0/vector-search/endpoints/dbdemos_vs_endpoint/indexes/main.rag_chatbot.databricks_documentation_vs_index

Here is the error message from the Delta Live Tables page. The pipeline fails to initiate with the following message:

DataPlaneException: Failed to start the DLT service on cluster 1212-013037-tgzej5mf. Please check the stack trace below or driver logs for more details.

Has anyone seen or solved this situation?

(Images will be updated, can't seem to upload them at the moment.
Instead you can go to this page and check 01-Data-Preparation-and-Index. The cell I mentioned is near the bottom.)

Hi, the best way to know is to open the DLT pipeline job and check the error you have here!

Answer 2 · 2023-12-12T07:31:56.000Z

Hi, the best way to know is to open the DLT pipeline job and check the error you have here!

Thanks for the reply. But the log pasted above is the error from the DLT pipeline.
It says something about the Metastore storage root URL not existing.
Any suggestions on how to solve this? Or should I be looking somewhere else?

Answer 3 · 2023-12-12T12:45:45.000Z

sorry I read that too quickly on my phone.
is your catalog/schema working properly,do you have data being written in your tables ? (can you do a select on your table & see the data before creating the index?)

Answer 4 · 2023-12-13T02:09:58.000Z

Yes, I followed the demo and created the databricks_documentation table inside main.rag_chatbot.
I can see the content from the Sample Data tab, and from the cell in the demo which executes a spark query to show the table.

Answer 5 · 2023-12-13T03:30:48.000Z

This is the standard error log from the Delta Live Tables workflow.

ANTLR Tool version 4.8 used for code generation does not match the current runtime version 4.9.3

I tried to update the version, but could not access the compute (cluster).
Could this be the problem? If so, how can I fix this?

hey @dkim94 , I checked with our team and it looks like something isn't properly setup with your metastore.
I'd double check the permissions (https://docs.databricks.com/en/data-governance/unity-catalog/create-metastore.html#step-2-create-an-iam-role-to-access-the-storage-location)
If it's still not working could you reach out the support or your account team? They'd be able to provide better help!
