Allen Wittenauer commented on HADOOP-6685:
------------------------------------------
(side note: i really hate the unexpected side effects that the jira text editor
can invoke. It clearly doesn't like exclamation points. I'd go back and fix
it, but since I don't have edit privs...)
BTW, I can't find the JIRA, but I know the HDFS guys were thinking along the
lines of supporting pretty much any character they throw at it, similar to how
most POSIX file systems work. It is interesting to think how that arrangement
will impact the MR side of the house....

> Currently, the generic serialization framework uses Map<String,String> for
> the serialization specific configuration. Since this data is really internal
> to the specific serialization, I think we should change it to be an opaque
> binary blob. This will simplify the interface for defining specific
> serializations for different contexts (MAPREDUCE-1462). It will also move us
> toward having serialized objects for Mappers, Reducers, etc (MAPREDUCE-1183).
