> 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.
