<p>superset creates and uses an sqlite database at <code class="docutils literal"><span class="pre">~/.superset/superset.db</span></code>. Sqlite is known to <a class="reference external" href="https://www.sqlite.org/lockingv3.html">don&#8217;t work well if used on NFS</a> due to broken file locking implementation on NFS.</p>
<p>One work around is to create a symlink from ~/.superset to a directory located on a non-NFS partition.</p>
<p>Another work around is to change where superset stores the sqlite database by adding <code class="docutils literal"><span class="pre">SQLALCHEMY_DATABASE_URI</span> <span class="pre">=</span> <span class="pre">'sqlite:////new/localtion/superset.db'</span></code> in superset_config.py (create the file if needed), then adding the directory where superset_config.py lives to PYTHONPATH environment variable (e.g. <code class="docutils literal"><span class="pre">export</span> <span class="pre">PYTHONPATH=/opt/logs/sandbox/airbnb/</span></code>).</p>
