Doug Cutting commented on HADOOP-6323:
--------------------------------------
> what key should be used in the metadata to specify the schema string.
This part was already implemented in HADOOP-6165. Currently the serialization
system is named by the "Serialization-Class" metadata key. The currently
supported values for this key are:
"org.apache.hadoop.io.serializer.WritableSerialzation",
"org.apache.hadoop.io.serializer.JavaSerialzation", and
"org.apache.hadoop.io.serializer.avro.AvroSerialzation". Writable and Java
serialization implementations use the key "Serialized-Class" to the name the
serialized Java class, and Avro's serialization implementation uses the key
"Avro-Schema" for the schema. These are currently stored by SequenceFile's
metadata.
So the proposal here adds no new metadata keys or values. It simply adds a new
method to the existing Serialization API, extending it to also support the
creation of raw comparators.
