Change subject: IMPALA-13411: Fix DCHECK fires for scan nodes that produce zero-length tuples ...................................................................... IMPALA-13411: Fix DCHECK fires for scan nodes that produce zero-length tuples Removed the DCHECK assertion that tuple_data_len must be greater than zero in tuple-file-writer.cc and tuple-file-reader.cc, because in certain cases, such as count(*), tuple_data_len can be zero, as no column data is returned and only the row count matters. Tests: Adds TestTupleCacheCountStar for the regression test.
