CLI list not working #1122

Open TiansuYu opened 2 months ago

TiansuYu commented 2 months ago

Apache Iceberg version

0.7.1 (latest release)

Please describe the bug 🐞

I am currently trying out the pyiceberg CLI, and found this command seems not working as expected: 

pyiceberg list --uri localhost:8181

returns 

URI missing, please provide using --uri, the config or environment variable PYICEBERG_CATALOG__DEFAULT__URI

The catalog instance is created from the official quickstart (can confirm it is working by spark-sql and connects to the minio instance and confirm data and metadata files are created correctly). If I understood it correctly, it exposes the catalog at 8181.

I have tried a dozens of others ports and urls (such as s3://warehouse), not working either. Seems the problem is that, the argument is simply not propagated into the config in the end somehow.

Looks like the catalog inference code requires the URI to include http in front

Still the same error:

pyiceberg list --uri http://localhost:8181
URI missing, please provide using --uri, the config or environment variable PYICEBERG_CATALOG__DEFAULT__URI

even if thats the case, the error message is a bit cryptic.

kevinjqliu commented 2 months ago

can you try

pyiceberg --uri http://localhost:8181 list

from https://py.iceberg.apache.org/cli/

➜ pyiceberg --help Usage: pyiceberg [OPTIONS] COMMAND [ARGS]...

agreed, the CLI needs some improvements

TiansuYu commented 2 months ago

Thanks, putting uri in front of commands worked! Another thing is 

-> % pyiceberg list --help                     
URI missing, please provide using --uri, the config or environment variable PYICEBERG_CATALOG__DEFAULT__URI

I would expect this will not attempting to make any connection calls, but simply print the help message

yea same, perhaps its some setting with the click lib

I would say load_catalog lazily until actually needed, in the main command.
