             Summary: Print the directory paths when ViewFs denies the rename operation on internal dirs
                 Key: HADOOP-13201
                 URL: https://issues.apache.org/jira/browse/HADOOP-13201
             Project: Hadoop Common
          Issue Type: Bug
          Components: viewfs
    Affects Versions: 2.7.2
            Reporter: Tianyin Xu


With ViewFs, the delete and rename operations on internal dirs are denied by throwing {{AccessControlException}}. 

Unlike the {{delete()}} which notify the internal dir path, rename does not. 

The attached patch appends the directory path on the logged exception.

     InodeTree.ResolveResult<AbstractFileSystem> resSrc = 
       fsState.resolve(getUriPath(src), false); 
     if (resSrc.isInternalDir()) {
       throw new AccessControlException(
-          "Cannot Rename within internal dirs of mount table: it is readOnly");
+          "Cannot Rename within internal dirs of mount table: it is readOnly"
+          + src);
     }
       
     InodeTree.ResolveResult<AbstractFileSystem> resDst = 
                                 fsState.resolve(getUriPath(dst), false);
     if (resDst.isInternalDir()) {
       throw new AccessControlException(
-          "Cannot Rename within internal dirs of mount table: it is readOnly");
+          "Cannot Rename within internal dirs of mount table: it is readOnly"
+          + dst);
     }
