Subject: [PATCH] [SPARK-17261] [PYSPARK] Using HiveContext after re-creating
SparkContext in Spark 2.0 throws "Java.lang.illegalStateException: Cannot
call methods on a stopped sparkContext"
## What changes were proposed in this pull request?
Set SparkSession._instantiatedContext as None so that we can recreate SparkSession again.
## How was this patch tested?
Tested manually using the following command in pyspark shell
```
spark.stop()
spark = SparkSession.builder.enableHiveSupport().getOrCreate()
spark.sql("show databases").show()
```
Author: Jeff Zhang <zjffdu@apache.org>
Closes #14857 from zjffdu/SPARK-17261.
