>             Project: Hadoop HDFS
>          Issue Type: Improvement
>          Components: caching
>    Affects Versions: 2.7.1
>            Reporter: Yiqun Lin
>            Assignee: Yiqun Lin

> In {{CacheReplicationMonitor#rescanCacheDirectives}}, it should recursively rescan the
path when the inode of the path is a directory. In these code:
> {code}
> } else if (node.isDirectory()) {
>         INodeDirectory dir = node.asDirectory();
>         ReadOnlyList<INode> children = dir
>             .getChildrenList(Snapshot.CURRENT_STATE_ID);
>         for (INode child : children) {
>           if (child.isFile()) {
>             rescanFile(directive, child.asFile());
>           }
>         }
>        }
> {code}
> If we did the this logic, it means that some inode files will be ignored when the child
inode is also a directory and there are some other child inode file in it. Finally the child's
child file which belong to this path will not be cached.
