KazydubB opened a new pull request #1614: DRILL-6962: Function coalesce returns an Error when none of the columns in coalesce exist in a parquet file
URL: https://github.com/apache/drill/pull/1614
 
 
   - Updated UntypedNullVector to hold value count when vector is allocated and transfered to another one;
   - Updated RecordBatchLoader and DrillCursor to handle case when only UntypedNull values are present in RecordBatch (special case when data buffer is null but actual values are present);
   - Added functions to cast UntypedNull value to other types;
   - Moved UntypedReader, UntypedHolderReaderImpl and UntypedReaderImpl from org.apache.drill.exec.vector.complex.impl to org.apache.drill.exec.vector package.
