----------------------------------
Replacing orc-core-1.5.6 with orc-core-1.5.6-nohive will invoke Exception too.

There is only
org.apache.orc.TypeDescription.createRowBatch()Lorg.apache.orc.storage.ql.exec.vector.VectorizedRowBatch
in orc-core-1.5.6-nohive.jar.
It seems there is only one way that is taking a workaround.
