Research direction
Start by reproducing the Hive-to-RDS synchronization described in the issue, using a Hive table with many null fields and more than thirty columns. Inspect how DataX identifies the source fields and compare that result with the destination schema; done means all fields are recognized consistently and the export no longer fails.
