Alejandro Abdelnur commented on HDFS-2316:
------------------------------------------
I've been running tests to validate HTTP REST API compatibility between webhdfs
and hoop. Following the issues I've found.
* FileStatus JSON payload has elements that are not part of the FileStatus
interface. The WebhdfsFileSystem client expects those elements and fails if
they are not present. These elements are: localName, isSymlink, symlink. These
elements are not later used and they are lost when creating a FileStatus in
WebhdfsFileSystem. Either those elements should not be in JSON payload (my
preference) or they should not be required by the WebhdfsFileSystem.
* delete, rename, mkdirs, setReplication JSON responses use 'boolean' as
element name, they should use the operation name as it is more descriptive.
* FileChecksum JSON serialization is using the classname in the JSON payload,
it should not, it should be something like:
{code}
{
"algorithm" : "foo",
"bytes" : "hexabytes",
"length" : 1000
}
{code}
* Same as FileChecksum JSON for ContentSummary JSON.

> We current have hftp for accessing HDFS over HTTP. However, hftp is a
> read-only FileSystem and does not provide "write" accesses.
> In HDFS-2284, we propose to have webhdfs for providing a complete FileSystem
> implementation for accessing HDFS over HTTP. The is the umbrella JIRA for
> the tasks.
