[jira] [Created] (HADOOP-12344) validateSocketPathSecurity0 message could be better

Casey Brotherton created HADOOP-12344:
-----------------------------------------

             Summary: validateSocketPathSecurity0 message could be better
                 Key: HADOOP-12344
                 URL: https://issues.apache.org/jira/browse/HADOOP-12344
             Project: Hadoop Common
          Issue Type: Improvement
          Components: net
            Reporter: Casey Brotherton
            Assignee: Casey Brotherton
            Priority: Trivial


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.
	at org.apache.hadoop.net.unix.DomainSocket.validateSocketPathSecurity0(Native Method)
	at org.apache.hadoop.net.unix.DomainSocket.bindAndListen(DomainSocket.java:189)
...
{code}

The error message could also provide the socket path:
{code}
java.io.IOException: the path component: '/' is world-writable.  Its permissions are 0077.  Please fix this or select a different socket path than '/var/run/hdfs-sockets/dn'
{code}
