Major Description
As described in the parent issue, we need a simple method to handle service dependencies in kubernetes clusters (usually as a workaround when some clients can't re-try with renewed dns information).
But it also could be useful to minimize the wait time in the docker-compose clusters.
The easiest implementation is modifying the started script of the apache/hadoop-runner base image and add a bash loop which checks the availability of the TCP port (with netcat).
