Currently, the ORC core and mapreduce jars depend on Hive's storage-api 2.2, which is incompatible with Hive 1.x. I'm proposing making shaded versions that:
- shade the storage-api into org.apache.orc.storage
- shade protobuf into com.google.protobuf25
Hive 1.x uses protobuf 2.5, like most of the Hadoop ecosystem, but taking the opportunity to remove it as a problem seems like a good idea.
