> Currently, LazySimpleSerde cannot handle columns including newline character cause hadoop
splits rows by newline character. If the overhead counting fields by full scan and merging
partial lines is tolerable, multi-lined column can be reconstructed at runtime.
> But with this method, multi-lined column should not be located at the last of the row.
This is just a idea for HIVE-1898.
