Erhan Kesken commented on MESOS-3136:
-------------------------------------
both mesos-docker-executor and mesos-health-check binaries are under
/usr/libexec/mesos folder.
before passing --launch-dir to mesos-slave, mesos-docker-executor was failing,
launch_dir fixed that problem but at next step health_check failed.
when I checked code at
https://github.com/apache/mesos/blob/5058fac1083dc91bca54d33c26c810c17ad95dd1/src/docker/executor.cpp#L573,
I concluded that --launch-dir parameter does not set MESOS_LAUNCHER_DIR
environment variable.
I removed --launch-dir parameter and put MESOS_LAUNCHER_DIR enviroment setting
to mesos-slave process by editing /etc/default/mesos-slave file. I confirmed
new enviroment setting is active by checking /proc/XXXX/environ file.
mesos-docker-executor did not fail like I passed --launch-dir parameter, but
mesos-health-check failed again.
I checked mesos-docker-executor process environment from proc, but
MESOS_LAUNCHER_DIR was not there. finally I solved problem by putting
environment variable to my marathon config after understanding health checks
are running inside docker.
