When importing data through insert, the data is filtered out

[LJ1An]

Steps to reproduce the behavior (Required)

INSERT OVERWRITE 【db_name.table_name】 WITH LABEL insert_load_table_name SELECT column1,column2,...... FROM 【mysql_catalog.db_name.table_name】

Expected behavior (Required)

The number of rows for 【db_name.table_name】 and 【mysql_catalog.db_name.table_name】 is the same

Real behavior (Required)

 【db_name.table_name】 has less data than 【mysql_catalog.db_name.table_name】. Some data has been filtered, and by checking the value of field trackingSQL in command 【show load from db_name where label like 'insert_load_table_name'】, it was found that it was due to some column length values in table【mysql_catalog.db_name.table_name】 exceeding the maximum value of varchar.
 I would like to add an optional configuration where when the length value of a field exceeds the maximum value of varchar, the field value is set to null instead of filtering out the entire row.
