Allow setting of install folder using env var

[daniddelrio]

Is it possible to allow users of this action to set the install directory themselves, maybe using an env var like SPARK_INSTALL_DIR? This way, we also have control over where to set the SPARK_HOME.

We have our own cache directory in our runners so we would like to set it there 🙂

@vemonet can you take a look?

@daniddelrio I have added an input param to define the install folder (where the SPARK_HOME folder will be downloaded and unzipped)

- uses: vemonet/setup-spark@v1
  with:
    spark-version: '3.5.3'
    install-folder: '/home/runner/work'

cf. https://github.com/vemonet/setup-spark/blob/main/src/setup-spark.ts

@vemonet perfect, thank you! So just to confirm, setup-spark@v1 will already have the install-folder input when I reference it from my workflows?

[daniddelrio]

Will it be possible to pass it as an env var as well rather than an install-folder input? This would make it easier for our setup as we have multiple workflows that reference this and we can simply set a global env var for all of our runners

[vemonet]

Yes it is available on v1 directly

Otherwise you could use the $GITHUB_WORKSPACE env variable (we try to use the parent of this folder, if not writable we directly use this folder): https://github.com/vemonet/setup-spark/blob/main/src/setup-spark.ts#L22
