Description

HDFS-4340 introduced a new field fileId in WebHDFS FileStatus JSON representation.

There are a two issues with this:

• This is changing the WebHDFS REST API, this has not been documented
• WebHdfsFileSystem should not fail when that field is not present (This is the case when using HttpFS against a FS implementation other than HDFS which does not handle fileId)
