---------------------------------
Summary: Override sameResult in HiveTableScanExec to make
ReusedExchange work in text format table
Key: SPARK-17425
URL: https://issues.apache.org/jira/browse/SPARK-17425
Project: Spark
Issue Type: Bug
Reporter: Yadong Qi
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), PhysicalPlan contain *ReuseExchange* in PhysicalPlan.
I found the *sameResult* in *FileSourceScanExec* has already overrided, but
*HiveTableScanExec* didn't,
