Xuefu Zhang commented on HIVE-8868:
-----------------------------------
Seems similar to HIVE-7593. Nevertheless, spark client should be user-session
specific. However, in case of local mode, user sessions "should" share the same
SparkContext instance, due to the concurrency problem in SparkContext.

> It should be a seperate spark context for each user session, currently we
> share a singleton local spark context in all user sessions with local spark,
> and create remote spark context for each spark job with spark cluster.
> To binding one spark context to each user session, we may construct spark
> client on session open, one thing to notify is that, is SparkSession::conf is
> consist with Context::getConf?
