Diff between patch 11 and patch 12:
spelling error:
< + * a token instance that is approriate for aliasing, or null if none. */
---
> + * a token instance that is appropriate for aliasing, or null if none. */
trap possibly hard to interpret errors fetching token without proper config:
> + if (!fetcher.isTokenRequired()) {
> + String message = "DtFetcher for service '" + service +
> + " does not require a token. Check your configuration. " +
> + "Note: security may be disabled or there may be two DtFetcher "
> + "providers for the same service designation.";
> + LOG.error(message);
> + throw new Exception(message);
> + }
{code}
> Updated utility to create/modify token files

> 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.
