Review comment:
Yeah I was trying to do that. Several reasons here:
1. AvroOrcSchemaConverter is now defined in gobblin-orc module, I don't
think it make sense for us to introduce new dependency for hive registration
module.
2. It's doable to transfer TypeDescription to TypeInfo, but it's the same
way that we need to use OrcUtils to create one objectInspector and get typeInfo
there. As we are using the writer schema to get orcSchema, I think the two
results should be the same? I verified one table and it looks good to me.
What do you think?
