Why does fabmanager or superset freezed/hung/not responding when started (my home directory is NFS mounted)?

One work around is to create a symlink from ~/.superset to a directory located on a non-NFS partition.
You can override this path using the ``SUPERSET_HOME`` environment variable.
Another work around is to change where superset stores the sqlite database by adding ``SQLALCHEMY_DATABASE_URI = 'sqlite:////new/localtion/superset.db'`` in superset_config.py (create the file if needed), then adding the directory where superset_config.py lives to PYTHONPATH environment variable (e.g. ``export PYTHONPATH=/opt/logs/sandbox/airbnb/``).
