Aaron Kimball commented on HADOOP-6438:
---------------------------------------
In MAPREDUCE-1126 you suggested that we add these methods directly to
WritableSerialization and AvroSerialization. We could move them into the MR
project proper, though I don't know that {{o.a.h.m.lib.input}} makes much sense
as a destination -- these methods are configuring the intermediate data types,
not the input types.
For future-proofing purposes: I anticipate that for MAPREDUCE-815, we'll also
need to add related methods to set the serialization metadata maps for the
final output key and value types. (a la {{JobConf.setOutputKeyClass()}}). It
would be nice if the output type configuration and the intermediate type
configuration remained "close together" (e.g., in the same package).
Should we add a new package that contains a configuration API around
serializers? e.g. {{o.a.h.m.lib.serialization}} or {{o.a.h.m.lib.types}}
> Add configuration getters/setters to serialization classes
