Ryan,

In Apache NiFi we have a ConvertAvroToOrc processor [1], you may find
code there that you can use in your Java program (take a look at line
212 and down). We had to create our own OrcFileWriter because the one
in Apache ORC writes to a FileSystem where we needed to write to our
own FlowFile component. But all the relevant code should be there (you
can replace the createWriter() call with the normal ORC one); one
caveat is that it's for Apache Hive 1.2, you may need to make changes
if you're using Hive 3 libraries for example.

Regards,
Matt
