Hi David,

We've had no problems running C* with supervisor, and your conf.d file is
broadly similar to ours. I don't think those errors are anything to do with
supervisor.

We did however have issues starting C* with the recommended resource
limits<http://www.datastax.com/documentation/cassandra/2.0/webhelp/index.html#cassandra/install/installRecommendSettings.html>;
if I remember correctly, the solution was to set supervisor's own defaults
appropriately (/etc/defaults/supervisor). Also watch out for
autostart/autorestart - if a node has been down for more than
max_hint_window_ms<http://www.datastax.com/documentation/cassandra/2.0/webhelp/index.html#cassandra/dml/../configuration/configCassandra_yaml_r.html#reference_ds_qfg_n1r_1k__max_hint_window_in_ms>you
may not want supervisor to automatically restart the daemon.

Good luck,

Robert
