Getting java.lang.NullPointerException at org.apache.thrift.transport.TSocket.open(TSocket.java:209) while creating hiveContext in Zeppelin.

I had installed HDP 3.0 which has Spark 2.3.1. I was running sql commands in Zeppelin notebook successfully but suddenly Windows update restarted the machine. When I opened the Zeppelin notebook again and ran the first command

%spark2
val hiveContext = new org.apache.spark.sql.SparkSession.Builder().getOrCreate()

I got following error logs: -

I am clueless. Request you to help me out of this issue. Thanks.

I restarted all the interpreters in settings section like :-

spark2,
angular
jdbc
livy2
md

and saved it.
Then re-run the code and it was successful. Thanks.
