James DeFelice commented on MESOS-4812:
---------------------------------------

would like to see some traction on this. several issues have been reported against Marathon,
the latest of which is https://github.com/mesosphere/marathon/issues/5136

>                 URL: https://issues.apache.org/jira/browse/MESOS-4812
>             Project: Mesos
>          Issue Type: Bug
>    Affects Versions: 0.25.0

> 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.
