Harsh J commented on HADOOP-12344:
----------------------------------
This would be very useful to add to make it easier to understand what path the
error's talking of. I know its pre-existed, but I wonder what's the use of
asking people to select a different path (bound to have the same problem
somehow).
Patch's changes look good, but I wonder if we should just drop that part of the
message and instruct better on how to fix it?
A message such as:
{code}
java.io.IOException: the path component: '/' in '/var/run/hdfs-sockets/dn' is
world-writable. Its permissions are 0077. Expected permission is XXX. Please
fix this.
{code}
(or similar) … would be more actionable, no?
> 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.

> The error message could also provide the socket path:

> permissions are 0077. Please fix this or select a different socket path than
