pitrou opened a new issue, #50991: URL: https://github.com/apache/arrow/issues/50991
### Describe the bug, including details regarding any error messages, version, and platform. The `conda-python` Crossbow build [detects and uses sccache](https://github.com/ursacomputing/crossbow/actions/runs/32845956751/job/97795558997): ``` -- Using sccache: /usr/local/bin/sccache ``` with actual cache hits: ``` === sccache stats after the build === Compile requests 482 Compile requests executed 482 Cache hits 128 Cache hits (C/C++) 128 Cache misses 354 Cache misses (C/C++) 354 Cache hits rate 26.56 % Cache hits rate (C/C++) 26.56 % Cache timeouts 0 Cache read errors 0 Forced recaches 0 Cache write errors 3 Cache errors 0 Compilations 354 Compilation failures 0 Non-cacheable compilations 0 Non-cacheable calls 0 Non-compilation calls 0 Unsupported compiler calls 0 Average cache write 0.094 s Average compiler 6.539 s Average cache read hit 0.044 s Failed distributed compilations 0 Cache location s3, name: ***, prefix: /sccache/ Version (client) 0.12.0 ``` but for some reason, the `debian-python` Crossbow build [doesn't detect sccache](https://github.com/ursacomputing/crossbow/actions/runs/32845958359/job/97795564439) and therefore falls backs on ccache with an empty cache: ``` -- Using ccache: /usr/bin/ccache ``` Yet, the `sccache` command seems to exist on the Docker image when run locally, and the GHA job defines the same environment variables (including `SCCACHE_BUCKET`). ### Component(s) Continuous Integration, C++ -- This is an automated message from the Apache Git Service.
