Casey Brotherton updated HADOOP-12344:
--------------------------------------
Attachment: HADOOP-12344.003.patch
Three copies of the newIOexception.
Also noticed and fixed a minor defect in the unit test.
It checks "/foo" off of the root directory to determine if the root
directory is secure, as it should be owned by root, and not world writable.
It does not fail, if you change the permissions of / to be world writable.
Made a change to the skipComponents parameter that seems to fix the behaviour,
and fail correctly while passing with normal root permissions.
> validateSocketPathSecurity0 message could be better

> When a socket path does not have the correct permissions, an error is thrown.
> That error just has the failing component of the path and not the entire path
> of the socket.
> The entire path of the socket could be printed out to allow for a direct
> check of the permissions of the entire path.
> {code}
> java.io.IOException: the path component: '/' is world-writable. Its
> permissions are 0077. Please fix this or select a different socket path.
