hi,
     I have a compressed file got from GetHDFS processor and to be unpacked by 
using UnpackContent processor, I have already set the UnpackContent processor 
property packaging format to 'tar', but an error like below always takes place.

The error logs is attached below (Unable to unpack StandardFlowFileRecord)

    My compressed file is named part-00002.gz, and you can access the file 
here: https://dl.dropboxusercontent.com/u/24808937/part-00002.gz
     Any advice would be welcome. Please help how to solve this problem, thank 
you!
