> In {{getINodesInPath4Write}}, the writes on snapshots are denied by throwing
> {{SnapshotAccessControlException}}.
> Unlike other file operations that print out the file path upon failure,
> {{getINodesInPath4Write}} does not.
> The attached patch appends the directory path on the logged exception.
> {code:title=ViewFs.java|borderStyle=solid}
> if (inodesInPath.isSnapshot()) {
> throw new SnapshotAccessControlException(
> - "Modification on a read-only snapshot is disallowed");
> + "Modification on a read-only snapshot is disallowed: "
> + + inodesInPath.getPath());
> }
> {code}
