无法将 Spark 制作为 Hive 执行引擎

Question

I am using Hive 3.1.2 and Spark 2.4.5(Hadoop 3 on Ubuntu 18.04) Getting below error while running queries

According to this error:
Caused by: java.lang.NoClassDefFoundError: org/apache/spark/SparkConf

Hive cannot find Spark classes.
If you're using Cloudera, you can add them with this command:

cd /opt/cloudera/parcels/CDH/lib;
cp  spark/jars/*scala-lib* hive/lib/;
cp  spark/jars/*spark-core* hive/lib/;
cp  spark/jars/*spark-netw*  hive/lib/;
cp  spark/jars/chill-java*.jar  hive/lib/;
cp  spark/jars/jackson-module-*  hive/lib/;
cp  spark/jars/jersey-server-*.jar  hive/lib/;
cp  spark/jars/json4s-ast_*.jar  hive/lib/;
cp  spark/jars/kryo-shaded-*.jar  hive/lib/;
cp  spark/jars/minlog-*.jar  hive/lib/;
cp  spark/jars/scala-xml_*.jar  hive/lib/;
cp  spark/jars/spark-launcher_*.jar  hive/lib/;
cp  spark/jars/spark-network-shuffle_*.jar  hive/lib/;
cp  spark/jars/spark-launcher_*.jar  hive/lib/;
cp  spark/jars/spark-unsafe_*.jar  hive/lib/;
cp  spark/jars/xbean-asm7-shaded-*.jar  hive/lib/;
