Hi Riini The source code for ORC is in org.apache.hadoop.hive.ql.io.orc package inside ql/src/java folder. The test cases corresponding to ORC are in ql/src/test folder under the same package structure. TestOrcFile should be a good starting point (for debugging) which reads/writes nested struct in ORC format.
