When deploying analytics refinery, we first perform a scap deploy, then we run an ad-hoc utility to push the files on HDFS refinery-deploy-to-hdfs.
refinery-deploy-to-hdfs uses git commands to know what files to send. It crashes when running an equivalent of a git status.
In fact, running git status in /srv/deployment/analytics/refinery fails with OSError: [Errno 13] Permission denied: '.git/fat/objects/tmpxUXHUu'
Providing write permission to other in .git/fat solves the problem temporarily. We did it on the test cluster.
