hi @the-other-tim-brown can you take a look, please?

daragu commented 1 month ago

hi @vinishjail97 can you help to take a look? thanks

the-other-tim-brown commented 1 month ago

I have 127.0.0.1 kubernetes.docker.internal added to /etc/hosts, I'm guessing that is how I'm able to make this work without these changes. I will try this out though on my machine and validate it works with the updates

the-other-tim-brown commented 1 month ago

I'm running into java.io.FileNotFoundException: File file:/home/data/db/hudi_dimCustomer/metadata/00001-64637ad8-218d-496d-aa33-52db8188727b.metadata.json does not exist right now. @daragu did you ever see something similar?

hi @vinishjail97, I think host.docker.internal is effective in Docker Desktop environment, but not in systems such as Linux.

@daragu can you squash your commits? I was able to confirm this is working after resetting some things on my local env.

Done, thanks.
