Manoj Govindassamy updated HADOOP-13828:
----------------------------------------
Attachment: HADOOP-13828.01.patch
Attaching v01 patch to take care of the following
* Implemented getFileChecksum(path, length) for ViewFileSystem
* Test to verify file checksum via ViewFileSystem is same as the target
FiileSystem
* Test needs the ChRootedFileSystem also implement the similar FileSystem's
getFileChecksum contract and it is folded in along with this change. Without
ChRootedFileSystem change, the test will fail.

> {{ViewFileSystem}} inherits the default implementation of
> {{getFileChecksum(final Path f, final long length)}} from FileSystem which
> returns null. ViewFileSystem must override this to resolve the target
> filesystem and file path from configured mount points and invoke the right
> checksum method on the target filesystem.
