我尝试编写了一个简单的代码,用于使用sparksql访问配置单元表:

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");
}

我在我的系统上运行了很多次这个特殊的程序,它运行得很好。但它突然停止工作,开始出错。

我在用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。我怎样才能摆脱它?好心的,帮帮我。问题是:

如果您正在使用sbt,则添加。。。。
在这里我提到了2.8.x,你也可以提到任何版本,这是在你的环境兼容2.5以上

// 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"

如果您使用的是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>
    <version>2.8.7</version>
</dependency>
