stack updated HBASE-3249:
-------------------------
Attachment: shutdown.txt
I took a quick look. 'help shutdown' is being interpreted as two commands, an
'help' followed by a 'shutdown'. The interpreter is running the 'shutdown'
command first and then 'help'. 'help' is a native IRB that we did some hackery
to override. The 'shutdown' is part of our command-set injection. I'd need to
dig in and spend some time figuring how I hacked this up.
For 0.90.0, I propose the following patch where we just remove the shutdown
command. Shutdown from inside the shell seems 'odd' to me. Meantime I'll open
an issue to look into how this help stuff is being interpreted by IRB. Its
kinda ugly. If you do 'help get' you get first complaint that get has not been
passed enough parameters and then the help output followed by the total help
output. Ugly. We need to fix. But don't think it blocker on 0.90 RC.

> _hp_ on IRC found out the bad way that typing 'help shutdown' actually gives
> you the full help... and shuts down the cluster. I don't really understand
> why we process both commands, putting against 0.90.0 if anyone has an idea.
