You can override this by editing conf/hadoop-env.sh. Both are optional,

wider distribution.
Yeah, I think it would be nice to find a workaround to explicitly using
these options.
Is adding the following line to your conf/hadoop-env.sh not good enough?
export HADOOP_SSH_OPTS=""
Or are you arguing that we should make that the default? I'd be okay
with that.
Instead of 'bin/start-all.sh' that's just 'bin/hadoop-daemon.sh start
namenode; bin/hadoop-daemons.sh start datanode'. Is that what you're
after? I guess we could add a bin/start-dfs.sh command that does this.
Yeah, that's exactly what I'm after. [ ... ] Anyways, getting back to the
point, yeah, it would be great to have something to just start and stop DFS,
and start and stop MapReduce for that matter, even if it just amounts to the
simple command you mentioned above. I've attached a quick patch for Hadoop
that implements it.
Can you please attach this to a bug so that we don't lose track of it?
Also, we should probably change the -all scripts to be based on the -dfs
and -mapred scripts, no?
