> hdfs fetchdt is missing some critical features and is geared almost 
> exclusively towards HDFS operations.  Additionally, the token files that are 
> created use Java serializations which are hard/impossible to deal with in 
> other languages. It should be replaced with a better utility in common that 
> can read/write protobuf-based token files, has enough flexibility to be used 
> with other services, and offers key functionality such as append and rename. 
> The old version file format should still be supported for backward 
> compatibility, but will be effectively deprecated.
> A follow-on JIRA will deprecrate fetchdt.
