我确实在Maven项目中将Spark版本从2.2.2升级到2.3.2,但收到以下错误:
Exception in thread "main" java.lang.NoClassDefFoundError: org/spark_project/guava/cache/CacheLoader
at org.apache.spark.SparkConf.loadFromSystemProperties(SparkConf.scala:75)
at org.apache.spark.SparkConf.<init>(SparkConf.scala:70)
at org.apache.spark.SparkConf.<init>(SparkConf.scala:57)
pom.xml文件包含以下依赖项:
<dependency>
<groupId>org.scala-lang</groupId>
<artifactId>scala-library</artifactId>
<version>2.11.12</version>
</dependency>
<dependency>
<groupId>org.apache.spark</groupId>
<artifactId>spark-core_2.11</artifactId>
<version>2.3.2</version>
</dependency>
<dependency>
<groupId>org.apache.spark</groupId>
<artifactId>spark-sql_2.11</artifactId>
<version>2.3.2</version>
</dependency>
我应该添加哪些依赖关系以消除Spark 2.3.2的此问题?
