Tom White commented on AVRO-1170:
---------------------------------
bq. To be clear, the current patch could be committed without the changes to
the pom and everything would still work with Hadoop 1, right?
Yes. I haven't tested that yet, but that's the idea.
bq. Would Hadoop 2 require recompilation?
Unfortunately it would. I found this out in MRUNIT-56 - the bytecode for method
invocation is different for classes and interfaces, so a separate JAR is needed
for each version.
