Manoj Govindassamy updated HADOOP-13885:
----------------------------------------
Attachment: HADOOP-13885.02.patch
Thanks for the review [~andrew.wang]. Can you please take a look at the updated
patch ?
Attached v02 patch to address the following
* Made {{ViewFileSystem#getLinkTarget}} throw NotInMountPointException when
internal mount point resolve fails and throw other exceptions including FNFE
from target filesystem as is.
* Updated ViewFileSystemBaseTest to verify both normal and relative symbolic
links, and added assume to skip irrelevant tests.
> Implement getLinkTarget for ViewFileSystem

> Project: Hadoop Common
> Issue Type: Task
> Components: viewfs
> Affects Versions: 3.0.0-alpha1

>
> ViewFileSystem doesn't override FileSystem#getLinkTarget(). So, when view
> filesystem is used to resolve the symbolic links, the default FileSystem
> implementation throws UnsupportedOperationException.
> The proposal is to define getLinkTarget() for ViewFileSystem and invoke the
> target FileSystem for resolving the symbolic links. Path thus returned is
> preferred to be a viewfs qualified path, so that it can be used again on the
> ViewFileSystem handle.
