Cyril Scetbon commented on CASSANDRA-8594:
------------------------------------------
bin/cassandra only sets the dedicated cassandra parameter
[here|https://github.com/cscetbon/cassandra/blob/cassandra-2.0.10/bin/cassandra#L139]
which doesn't write the pid at all. In 1.2, jsvc was used and it was this tool
that [was setting the
pid|https://github.com/apache/cassandra/blob/cassandra-1.2.13/debian/init#L136-L139].
But now that we don't use it (2.0+) we use
[start-stop-daemon|https://github.com/cscetbon/cassandra/blob/cassandra-2.0.10/debian/init#L96]
without asking it to create the pidfile. And as bin/cassandra says that it
[stores the
pid|https://github.com/cscetbon/cassandra/blob/cassandra-2.0.10/bin/cassandra#L21]
if we use -p pidfile, I think it's time to implement it in cassandra.
> pidfile is never filled by cassandra
