> About  'cache table as select'. In Spark1.5, I can run this sql for many times:  
> cache table t as select * from t1;  
> cache table t as select * from t2;  
> In Spark2.1 when I run the second sql will show "Error in query: Temporary table 't1' already exists;"  
> Why Spark2.1 don't support this sql??
