             Summary: Mesos fails to escape command health checks
                 Key: MESOS-4812
                 URL: https://issues.apache.org/jira/browse/MESOS-4812
             Project: Mesos
          Issue Type: Bug
    Affects Versions: 0.25.0
            Reporter: Lukas Loesche


As described in https://github.com/mesosphere/marathon/issues/3333
I would like to run a command health check
{noformat}
/bin/bash -c "</dev/tcp/$HOST/$PORT0"
{noformat}

The health check fails because Mesos, while running the command inside double quotes of a sh -c "" doesn't escape the double quotes in the command.

If I escape the double quotes myself the command health check succeeds. But this would mean that the user needs intimate knowledge of how Mesos executes his commands which can't be right.

I was told this is not a Marathon but a Mesos issue so am opening this JIRA. I don't know if this only affects the command health check.
