Github user felixcheung commented on the issue: https://github.com/apache/spark/pull/17941 @rxin it was from a while back in SPARK-17865 essentially these are exactly the same in standalone SparkR: ``` sparkR.session() ... createGlobalTempView(df, "foo") sparkR.session.stop() ``` same as ``` sparkR.session() ... createOrReplaceTempView(df, "foo") sparkR.session.stop() ``` this is because in SparkR, `SparkContext` is stopped the same time as `SparkSession` (and there is only one session at a time) so I think it makes sense to formally support the idea of the "global session" as discussed in SPARK-17865; with some changes in session initialization and session termination, and R session cleanup, plus more documentation and proper testing of global view lifetime beyond session, it should be good to have.
