Data Lineage in Unity Catalog not Populating

Ian_Neft — Fri, 10 Nov 2023 20:17:42 GMT

I have been trying to get the data lineage to populate with the simplest of queries on a unity enabled catalog with a unity enabled cluster. I am essentially running the example provided with more data to see how it works with various aggregates downstream.

CREATE OR REPLACE TABLE unity_metastore.lineage_test.table1_standard ( _id INT, food STRING, score DECIMAL, food_type STRING ); INSERT INTO unity_metastore.lineage_test.table1_standard (_id, food, score, food_type) VALUES (1, 'pizza', 9.5, 'italian'), (2, 'tacos', 8.7, 'mexican'), (3, 'pasta', 7.5, 'italian'), (4, 'burrito', 9.0, 'mexican'), (5, 'burger', 4.5, 'american'), (6, 'sourkraut', 2.4, 'polish'), (7, 'fried rice', 6.0, 'chinese'), (8, 'hot pot', 9.0, 'chinese'), (9, 'mole', 8.7, 'mexican'), (10, 'dim sum', 7.0, 'chinese') ; CREATE OR REPLACE TABLE unity_metastore.lineage_test.table2_standard AS SELECT _id, food, score, food_type FROM unity_metastore.lineage_test.table1_standard WHERE score > 5 ;

However when I go to the lineage tab on the tables (which I have all privileges for the catalog and every schema/table underneath it) they are blank. There is history being collected and data is showing up in them.

I am running a cluster with 13.3 LTS and the following runtime settings enabled

spark.databricks.dataLineage.enabled true

spark.databricks.delta.dataLineage.enabled true

spark.databricks.delta.columnMapping.mode true

Hi,

A few thoughts:

Can you confirm that the cluster is running in either Access Mode "Assigned" or "Shared"
You can confirm that UC is setup correctly using this guide: https://docs.databricks.com/data-governance/unity-catalog/index.html
Consider doing a full refresh on the Catalog explorer page to help eliminate any strange browser caching behaviors

And if you are looking to enable column mapping mode, it can be added as a `TBLPROPERTIES` to a table using:

'delta.columnMapping.mode' = 'name'

...or at a session, cluster level with: `spark.databricks.delta.properties.defaults.columnMapping.mode`.

I have exactly the same issue, create the sample tables , everything seems fine but I can not see any data in lineage tab page in databricks .

can anybody say some other thing to help me, because that answer doesn't work for me

You might need to update your outbound firewall rules to allow for connectivity to the Amazon Kinesis / Event Hubs endpoint.

Cluster running in shared mode with Databricks runtime 15.4 LTS

UC setup as per Databricks guide. I can see system tables everything but data is not populating in the table_lineage table. EventHub Firewall 9093 port is also open.

Enabled runtime settings as well

spark.databricks.dataLineage.enabled true

spark.databricks.delta.dataLineage.enabled true

spark.databricks.delta.columnMapping.mode true

still no luck. Any other thing that can be done or checked. Quickhelp is appreciated
