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(text format), PhysicalPlan contain *ReuseExchange* in
PhysicalPlan.
I found the *sameResult* in *FileSourceScanExec* has already overrided, but
*HiveTableScanExec* didn't,
was:
