* This fixes hadoop-daemons.sh and yarn-daemons.sh so that they work with multiple hosts.
The problem was two fold:
* We were not preserving quotes around parameters that contained $IFS due to lack of quoting around the array deletion
* The then deleted array elements were retained and show up as an empty argument.

> After introduction of "--slaves" option for the scripts, start-dfs.sh and stop-dfs.sh will no longer work in HA mode.
> This is due to multiple hostnames passed for '--hostnames' delimited with space.
> These hostnames are treated as commands and script fails.
> So, instead of delimiting with space, delimiting with comma(,) before passing to hadoop-daemons.sh will solve the problem.
