There is the process manager (tech preview in fuse 6.1) and further improved for 6.2 release
You can find details about it in the fabric8 upstream community project
The process manager can manage any kind of OS process. You can integrate with it, to define how a process should be started|stopped|killed|check status etc. And there is some examples in fabric8 out of the box, for cassandra, wildfly and other containers.
Thanks a lot, that is exactly what I was looking for !
