Joseph Fourny commented on SPARK-4815:
--------------------------------------

Is this really fixed? I am on Spark 1.5.0 (rc3) and I see very little isolation 
between JDBC connections to the ThriftServer. For example, "SET X=Y" or "USE 
DATABASE X" on one connection immediately affects all other connections. This 
is extremely undesirable behavior. Was there a regression at some point?

> ThriftServer use only one SessionState to run sql using hive, though it from 
> different hive sessions.
> This will make mistakes:
> For example, one user run "use database" in one beeline client. the database 
> in other  beeline change too.
