How to get git commit ID of the repository the script runs on?

[annagriv]

I have a script in a repository on DataBricks. The script should log the current git commit ID of the repository. How can that be implemented?

I tried various command, for example:

result = subprocess.run(['git', 'rev-parse', 'HEAD'], stdout=subprocess.PIPE, check=True)

but getting the following error:

Command '['git', 'rev-parse', 'HEAD']' returned non-zero exit status 128.

Any help with this will be appreciated 🙏

I think this is because of the fact that the code and execution (clusters) are separated.

Thanks for you reply, so this means its impossible to log the git commit id? There is no way to pass this information to the cluster?

I think that is indeed the case (not 100% sure as I do not know the innards of Databricks).

The on-demand cluster receives a program to be executed and I don't think a git history is passed.
