Steve Loughran updated HADOOP-5740:
-----------------------------------
Status: Patch Available (was: In Progress)
This makes the permissions collection writable, so does not trigger failures in
jetty or RMI code when trying to run with a security manager and a
ConfiguredPolicy as the current (static, system-wide) policy.
> Hadoop JSP pages don't work under a security manager
