2. After analysis and debugging, it was found that starting from savepoint
does not execute the JobMaster::handleSaveMode method, so the
handleSchemaSaveMode method of the PaimonSaveModeHandler class is not executed,
resulting in a null pointer error when writing paimon
3.The relevant code call stack is shown in the following figure:
