Patch Set 5: (1 comment) http://gerrit.cloudera.org:8080/#/c/7639/5/be/src/exec/hdfs-text-scanner.cc File be/src/exec/hdfs-text-scanner.cc: Line 297: boundary_column_.Clear(); > Can we use the existing CopyBoundaryField() function for consistency? Other I tried it and it doesn't quite work (without clearing the boundary field) This is a slightly different case. CopyBoundaryField() copies the contents of the field followed by the boundary column to memory allocated from the row batch. In this case, after FillColumns(), field_locations is pointing at the data in the boundary column. We can trick CopyBoundaryField() by clearing the boundary column right before CopyBoundaryField(), but it's such a weird thing to do. (It looks weird because we just cleared the boundary column, why are we trying to copy out of it?) Another thing we can do, is check that the field is pointing to a different memory location than the boundary column, but I also think that's weird. I suggest we leave it as is (for me, the way it is now is the least confusing way).
