Yadong Qi updated SPARK-17425: ------------------------------ Description: When I run the below SQL(table src is text format): {code:sql} SELECT 1 FROM src t1 JOIN src t2 ON t1.key = t2.key JOIN src t3 ON t1.key = t3.key; {code} The PhysicalPlan doesn't contain *ReuseExchange*. And I use src_pqt(parquet format) instead of src, PhysicalPlan contain *ReuseExchange* in PhysicalPlan. I found the *sameResult* in *FileSourceScanExec* has already overrided, but *HiveTableScanExec* didn't, was: When I run the below SQL(table src is text format): {code:sql} SELECT 1 FROM src t1 JOIN src t2 ON t1.key = t2.key JOIN src t3 ON t1.key = t3.key; {code} The PhysicalPlan doesn't contain *ReuseExchange*.
