Kate Rhodes commented on HADOOP-1954:
-------------------------------------
you're right it should be singular instead of plural to just start it on this node. Why we need it? for the same reason we need any of the simple start stop scripts. To save typing. Plus it makes life easier for newbs like me. There's scripts for starting all the other things but when you're starting out it seems likely than one of the things you're going to be doing is setting up task trackers on nodes. Having a script right there in the bin dir that does it for you helps get you up and running faster and gives new users one less hurdle to get over. It wasn't at all obvious to me how to start just a task tracker.
These aren't "needed" but they're nice to have, don't really get in the way of anything, and can make life easier for new users before they get frustrated and go away.

Doug Cutting commented on HADOOP-1954:
--------------------------------------
This is just 'bin/hadoop-daemon.sh start tasktracker' no? Why do we need a separate script for that? Also, in your patch you use 'hadoop-daemons.sh' (plural) which will run a tasktracker on each slave node, rather than just on the current node.
