If I understand correctly
from pyspark.sql import SparkSession
from pyspark import SparkContext
from pyspark.sql import SQLContext, HiveContext
import sys
def spark_session(appName):
return SparkSession.builder \
.appName(appName) \
.enableHiveSupport() \
.getOrCreate()
def sparkcontext():
return SparkContext.getOrCreate()
def hivecontext():
return HiveContext(sparkcontext())
