Attachment: Session management in Spark SQL 1.6.pdf
Design doc
> Improve session management for SQL
> ----------------------------------
>
> Key: SPARK-10810
> URL: https://issues.apache.org/jira/browse/SPARK-10810
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Reporter: Davies Liu
> Assignee: Davies Liu
> Priority: Blocker
> Attachments: Session management in Spark SQL 1.6.pdf
>
>
> Currently, we try to support multiple sessions in SQL within a Spark Context,
> but it's broken and not complete.
> We should isolate these for each session :
> 1) current database of Hive
> 2) SQLConf
> 3) UDF/UDAF/UDTF
> 4) temporary table
> For added jar and cached tables, they should be accessible for all sessions.
