ctubbsii opened a new issue #422: Token file functionality for mapred code deprecated, but not replaced
URL: https://github.com/apache/accumulo/issues/422
 
 
   As fallout from the recent Connector builder stuff that @mikewalch worked on for 2.0, many of the old APIs were deprecated in the MapReduce code to be replaced with `ConnectionInfo`. However, the mapreduce APIs for storing an authentication token in a job's distributed cache, and reading it from within the mappers does not have an equivalent in the new code.
   
   What is needed is two things:
   
   1. The ability to serialize the entire connection info into the job, without exposing the credentials in the Hadoop configuration, and
   2. The ability to serialize arbitrary authentication tokens, not just the known ones that the current Connector builder has special code to handle. (A whole authentication token serializer was previously created for this purpose, but it is not used in the new code.)
