… discovery The local Docker interop build failed with "Multiple top-level packages discovered in a flat-layout: ['avro', 'userlogs']". The Hadoop tether tests leave a userlogs/ directory next to the avro/ package, which breaks setuptools automatic flat-layout package discovery. Explicitly scope package discovery to avro* so stray directories such as userlogs/ are ignored.

What is the purpose of the change
This pull request fixes the local/Docker Python interop build, which fails with:
The Hadoop tether tests leave behind a
userlogs/directory next to theavro/package. Becausepyproject.tomldid not configure packagediscovery, setuptools falls back to automatic flat-layout discovery, sees
two top-level packages (
avroanduserlogs), and refuses to build. Thisdoes not surface in GitHub Actions because each language is tested in
isolation and the tether tests never create
userlogs/there.The fix explicitly scopes setuptools package discovery to
avro*, so straydirectories such as
userlogs/are ignored. This resolves AVRO-4308.Verifying this change
This change is already covered by the existing interop test targets:
