Yup, that's the pattern.
For example, after committing HADOOP-11565, my startup looks like this:
{code}
$ hadoop --slaves version | grep repo
$ hdfs namenode -format
$ hdfs --daemon start namenode
$ hdfs --slaves --daemon start datanode
$ yarn --daemon start resourcemanager
$ yarn --daemon start proxyserver
$ yarn --slaves --daemon start nodemanager
{code}
Of course, you can do fancier things now that all of the -- options are
supported on slaves.... (i.e., yarn --slaves --hosts="proxyhost" --daemon start
--config /my/customfig --debug proxyserver will start the proxyserver on the
host proxyhost with the custom config in debug mode.)
I need to fix sbin/(start|stop) yet, but they'll turn into wrappers around
these commands, eliminating about 4 levels of shell indirection vs. branch-2...
