-----------------------------------------
Summary: mesos slave should handle a PID file
Key: MESOS-1999
URL: https://issues.apache.org/jira/browse/MESOS-1999
Project: Mesos
Issue Type: Bug
Components: slave
Reporter: Tobias Weingartner
At the current time, we use extra tooling around the mesos-slave to create and
manage a pid file for the slave (and master). This tooling is brittle at best,
and it would be very nice if the mesos-slave could create, remove, and manage a
pid file on its own.
In particular, it could use flock(2) to lock the file while it is running,
giving an extra signal to any other slaves starting up that there is a live
mesos-slave currently running (along with kill(2) with signal 0 to probe).
