我尝试编写一个使用SparkSql访问Hive表的简单代码:
SparkSession spark = SparkSession.builder()
.appName("Java Spark Hive Example")
.master("local[*]")
.config("hive.metastore.uris", "thrift://localhost:9083")
.enableHiveSupport()
.getOrCreate();
try{
Dataset<Row> df = spark.sql("select survey_response_value from health");
df.show();
} catch (Exception AnalysisException) {
System.out.print("\nTable is not found\n");
}
我在我的系统上多次运行这个特定程序,运行正常。但突然间它停止工作并开始出错
以下是错误和跟踪的完整列表:

我正在使用IntelliJ。
我没有对依赖项或代码做任何事情。所以我不明白是什么让代码不起作用。我怎么能摆脱它?请帮助我。 这是问题所在:

如果您使用SBT,请添加....
在这里我提到了2.8.x你还可以提到任何在2.5以上的环境中兼容的版本
// https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-core
libraryDependencies += "com.fasterxml.jackson.core" % "jackson-core" % "2.8.7"
// https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-databind
libraryDependencies += "com.fasterxml.jackson.core" % "jackson-databind" % "2.8.7"
如果你正在使用maven
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>2.8.7</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
