Sparksession error is about hive - hadoop

Question

My OS is windows 10
from pyspark.conf import SparkConf
sc = SparkContext.getOrCreate()
spark = SparkSession.builder.enableHiveSupport().getOrCreate()
This code gives me below error

From the code you posted it seems you are a Java developer or maybe you were in a hurry to paste the code. In python, you do not write variables with their types like we do in Java i.e
SparkContext sc =SparkContext.getOrCreate().
Also, starting from Spark version 2.0+, you need to create a SparkSession object which is the entry point to your application. you derive your SparkContext from this object itself. Trying to create another SparkContext "sc = SparkContext.getOrCreate()" results in errors. This is due to the fact that by design, only a single SparkContext can run in a given single JVM. if a new Context is required you need to stop the previously created SparkContext with sc.stop().
That being said from your stack-trace and code I also think you are testing your app locally and do not have a Hadoop and Hive installation on your local machine which is giving you the error:
Caused by: java.lang.RuntimeException: java.lang.RuntimeException:
Unable to instantiate
org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient at
org.apache.hadoop.hive.ql.session.SessionState.start(SessionState.java:522)
at ...
You can install Hadoop and Hive on your Windows machine and try out the following code snippet.
from pyspark.sql import SparkSession
spark = SparkSession \
.builder \
.appName('CalculatingGeoDistances') \
.enableHiveSupport() \
.getOrCreate()
sc = spark.sparkContext
