Eli Collins commented on HADOOP-7089:
-------------------------------------
bq. Does this work on OSX, BSD, and Solaris? I seem to remember this being
proposed before, but killed for compatibility reasons.
I checked that -m and -n were supported on Solaris. Looks like from
ZOOKEEPER-303 though that OSX doesn't have this option, think the same
workaround is acceptable here?
