Xuefu Zhang commented on HIVE-8528:
-----------------------------------

It's mainly for HiveSever2, where there are concurrent client sessions, each 
having its SparkContext object. SparkContext is heavy, putting memory pressure 
on HiveServer2, proportionally to the number of active client sessions. With 
remote SparkContext, the pressure is transfered to remote process.

> Add remote Spark client to Hive [Spark Branch]

> For the time being, at least, we've decided to build the Spark client (see 
> SPARK-3215) inside Hive. This task tracks merging the ongoing work into the 
> Spark branch.
