I suggest on your HDFS server you start a process (using shellscript for example) to execute kinit and after that, get these remote files using sftp or scp example
# scp user@remoteserver:/remotepath/files localpath/
and
# hdfs dfs -put localpath/files /hdfspath
Note: To automate this process you can create a private/public ssh between these servers and create a crontab entry.
