Allen Wittenauer commented on HADOOP-9902:
------------------------------------------
bq. Doesn't the following from old script print warning and delegate nfs3 and
portmap to hdfs script?
It does. But if you notice, all of those other commands were in Hadoop 1.x...
before the hdfs command existed. portmap and nfs3 came way way way after that.
In other words, running e.g. 'hadoop portmap' as a command was never
documented as valid. So the only way someone would run that would be
accidentally. If we do that for every command that someone might accidentally
run, we're gonna be in for a bad time.
