> When enabling the *webinterface.private.actions* property to true, the JobTracker displays additional buttons allowing the user to (1) kill jobs or (2) change the priority of a job.  However, an erroneous interaction between the HTML (produced by mapred/JSPUtil.java) and sorttable.js leads to these two form buttons having no effect because the {{<form>}} {{</form>}} is moved down below the submit buttons (by sorttable.js). sorttable.js was introduced by MAPREDUCE-1118 (so all versions from v0.20.203 are probably affected). In JSPUtil.java, the form element is placed inside the table and spans multiple {{<tr>}} and {{<td>}} which is incorrect. Placing the form around the table fixes this bug (see patch)
