Jacob Rideout commented on MAPREDUCE-815:
-----------------------------------------
What is the current line of thought on how keys and values will interact with
the schema for an avro file? Is the intention that there would be a master
schema that encapsulated the key/values similar to:
{code}
{ "type" : "record",
"fields" : [
{ "name" : "KEY", "type" : "record" },
{ "name" : "VALUE", "type" : "record" }
]}
{code}
What about files created without this "master" schema; would the key return a
null object? Byte offset in a schema of type "long" ?
