I verified it with MB 53 and 1.53.2, and it works as expected.

This looks odd:

java.lang.NoClassDefFoundError: Could not initialize class metabase.driver.clickhouse

Could you check if the driver jar is correctly put to plugins directory?

Mar 17 '25 19:03 slvrtrn

I'm using the clickhouse driver in Metabase Cloud, and since saturday it has a lot of problemas

The cache feature stopped working, and I had to disable it. That's not a big deal, and after disabling it, the dashboads began loading again

Now, between yesterday and now, nothing loads again, no dashboard, no question, nothing..

My company is built entirely on top of metabase dashboards using clickhouse data, I really really need urgent help!

Same error, different version of the driver: Metabase v0.53.5 (run on docker) Clickhouse v25.1.5 (run on docker) Driver v1.53.3 (worked fine with driver v1.53.2 though)

So it's quite odd my side... I tried to rebuild my docker image and deploy on 2 different K8 cluster: one worked and the other showed the same error. So somehow it's dependent on maybe the config used on Metabase, although mines are very close to each other. I couldn't spot anything explaining it. I then re-created my failing pod and it worked.

I suspect something with the way the classpath is initialised where the order of loading classes is not guaranteed.

Could you check if the driver jar is correctly put to plugins directory?

Yes it is:
