Description
getRowNumber() is required to read data in non-acid tables that were converted to acid.
Currently when VectorizedOrcAcidRowBatchReader is used from LlapRecordReader this functionality is not available making it impossible to vectorize reads (that need ROW__ID)/updates of non-aicd-to-acid tables with LLAP (until major compaction) in the presence of any deletes.
