Kai Zheng commented on HADOOP-12924:
------------------------------------
OK, it won't be bad to have a policy for the legacy coder, since we would have
one for the dummy coder. So, what's needed for now would be, a mapping between
{{codec-name}} and {{raw-coder-factory-class}}. In the original design by
HDFS-7337, it would be done by {{ErasureCodec}}, but for phase 1 and right now,
for simple we can have a simple enum or hard-coded mapping codes somewhere. For
the legacy and dummy policies, we just hard-code the raw-coder-factory class;
for the default RS policy, in addition to the hard-coded default raw coder, we
allow to configure the class just as current code does using the default coder
key. Sounds good?
> Add default coder key for creating raw coders
