## Known Issues

This section contains a list of known issues reported in Kubernetes 1.9 release. The content is populated from the [v1.9.x known issues and FAQ accumulator] [#57159](https://github.com/kubernetes/kubernetes/issues/57159).

 * resources are files and directories however an <code>SmbFile</code>
 * may also refer to servers and workgroups. If the resource is a file or
 * directory the methods of <code>SmbFile</code> follow the behavior of
 * the well known {@link java.io.File} class. One fundamental difference
 * is the usage of a URL scheme [1] to specify the target file or
 * directory. SmbFile URLs have the following syntax:
