> The "swstatus" script used in cases where we did install_local_hadoop counts 
> the MySQL processes and then simply invokes jps.
> It would be better if the script would check specifically for HMaster, 
> NameNode, DataNode and maybe others, like NodeManager and ResourceManager. If 
> any are missing, it should print out which ones are missing, otherwise it 
> should just say something like "processes are up".
> It should also return an exit code of 0 if everything is up and 1 if some 
> processes are missing.
