Better safety of killing jobs via web interface
-----------------------------------------------
Key: HADOOP-3342
URL: https://issues.apache.org/jira/browse/HADOOP-3342
Project: Hadoop Core
Issue Type: Improvement
Affects Versions: 0.16.3
Reporter: Daniel Naber
Priority: Minor
Attachments: kill-job.diff
Although the option to kill jobs via the web interface is turned off by
default, it should be made safer. Currently the "kill" action and its
confirmation is just a link so it could be triggered by a crawler or by a
browser's pre-fetching mechanism. The attached patch makes it work only with
"POST" so that e.g. well-behaved crawlers shouldn't be able to access it.
