eric baldeschwieler commented on HADOOP-5643:
---------------------------------------------

Do we have a good security story for actions taken through the web UI?  Absent that, I'd suggest we don't enable this there.

Being able to modify the excludes file and hup the server is probably good enough for an operator.

> Its not always possible to shutdown the tasktracker to stop scheduling tasks on the node. (eg you can't login to the node but the TT is up). 
> This can be via 
>   * mapred.exclude and should be refreshed with out restarting the tasktracker
>   * hadoop job -fail-tracker <tracker id>
