> Currently org.apache.gobblin.util.hadoop.TokenUtils#getHdfsToken adds the
> DistributedFileSystem's delegation token to the Credential's object. However,
> if the DFS is federated, then only one token for the primary name node is
> fetched and tokens for child namenodes are not fetched.
> Hence this method needs to be updated to use
> org.apache.hadoop.fs.FileSystem#addDelegationTokens instead of
> org.apache.hadoop.fs.FileSystem#getDelegationTokens which automatically
> fetches the delegation tokens for all child FS as well.
