Datahub Ingestion Issues with Impala Hive Connector and SQLAlchemy Recipes

user-3 · March 4, 2024, 3:52pm

Hi Team -
We are on datahub version 0.10.5. Though this problem below has been present since much before.
We are ingesting some Hive tables from Apache Impala using the Hive connector. The ingestion jobs have several errors regarding not able to ingest metadata. In datahub UI, we see the tables are present but without any schemas.
Below are some of the errors we see -

It seems pyhive doesn’t support fully Impala.
Maybe you can try out the generic sqlalchemy source with impyla

user-3 · March 4, 2024, 3:52pm

ok we’ll try that

user-3 · March 4, 2024, 3:52pm

source:
type: sqlalchemy
config:
platform: "hive"
include_views: true
env: PROD
platform_instance:
connect_uri: "impala://"

sink:
type: "datahub-rest"

This is the recipe we are already using. I believe this is the sqlalchemy source with impyla ? If so, then it is not working and throwing the above errors. <@UV14447EU>

Can someone help us here please? Our SQLAlchemy recipe to Hive source using impala is not able to get metadata for many source tables and also for the ones its able to ingest, the schema fields details are missing.

Does impala have sqlalchemy driver? Maybe you can try with that and the generic sqlalchemy source.

user-2 · March 4, 2024, 3:52pm

<@UV14447EU> I have even tried with hive connection and it gives different error

user-2 · March 4, 2024, 3:52pm

here is the code

Hello <@UV14447EU> , did you get chance to look into the above issue

user-2 · March 4, 2024, 3:52pm

Hello <@UV14447EU>, can you help us here

datahub_team · March 4, 2024, 3:52pm

I’m afraid if neither Hive source and nor vanilla SqlAlchemy source works with Impala then I’m afraid we need a custom source with the official Impala sqlalchemy driver (does this exists??).
