   > Gluten's implementation is the same as vanilla Spark's. Just out of 
curiosity, can Spark pass this failed test?
   
   Vanilla Spark does share the same hash relation, but it does not drop 
duplicates, so the two types of joins will not generate data issue. But Gluten 
native build hash table will drop duplicates for the `LEFT SEMI JOIN`, and the 
hash table is reused by the `INNER JOIN`, which cause the issue.
