Connect to multiple hive metastore using single sparkcontext (i.e without stopping it")

I wanted to join 2 hive tables which are stored in 2 different hive metastores.
I would like fetch the first table, create a tempview. Change hive metastore uri, connect to that metastore and fetch the second table , create a tempview and then use tempviews to do further. 

I launched 2 different instances of hive on my local , individually i'm able to connect to both, but when i try to connect to them one after other, the second time the old URI's is getting used.

Any workaround this.

Please help out :\
