>    Affects Versions: 3.0.0

> 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.
