[jira] [Created] (ORC-244) WriterImpl::writeBatch() should throw an assertion for isSelectedInUse=true

Gopal V created ORC-244:
---------------------------

             Summary: WriterImpl::writeBatch() should throw an assertion for isSelectedInUse=true
                 Key: ORC-244
                 URL: https://issues.apache.org/jira/browse/ORC-244
             Project: ORC
          Issue Type: Bug
            Reporter: Gopal V


Since TreeWriterBase::writeBatch does not understand selection vectors - this needs to throw an exception instead of writing irrelevant rows out to the file format.

This codepath is not exercised by Hive today, because it uses the writeRow() which removes the selection vectors from being setup.
