> After change a table's bucket num in table store,I used a insert overwrite sql to reorganize records to new files (I guess form old orc file to the new).
> Everytime if select column contains the partition column,then get the next exception:

> When exclude the partition field,it do perform the overwrite.
> I wonder the “EXPR$3: STRING NOT NULL” means what ,
