Sparksession error is about hive

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

Py4JJavaError Traceback (most recent call last) ~\Documents\spark\spark-2.1.0-bin-hadoop2.7\python\pyspark\sql\utils.py in deco(*a, **kw) 62 try: ---> 63 return f(*a, **kw) 64 except py4j.protocol.Py4JJavaError as e:

My full code is here

from pyspark.sql import SQLContext 
from pyspark.sql import SparkSession 
import findspark 
findspark.init('C:/Users/asus/Documents/spark/spark-2.1.0-bin-hadoop2.7') 
import pyspark from pyspark.conf 
import SparkConf sc = SparkContext.getOrCreate() 
spark = SparkSession.builder.enableHiveSupport().getOrCreate()

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

Sparksession error is about hive
