Question

我有一个进行GeoIP查找的配置单元UDF。

public static Text evaluate(Text inputFieldName, Text option,
        Text databaseFileName) {

    String inputField, fieldOption, dbFileName, result = null;

    inputField = inputFieldName.toString();
    fieldOption = option.toString();
    dbFileName = databaseFileName.toString();
    ExtractData eed = new ExtractData();
    try {
        result = eed.ExtractDB(inputField, fieldOption,
                dbFileName);
    } catch (IOException e) {
        e.printStackTrace();
    } catch (GeoIp2Exception e) {
        e.printStackTrace();
    }
    return new Text(result);

}

然后我从中制作了一个罐子并在hive Cli中运行以下内容

add jar /location_of_jar/MyUDF.jar;
add file /user/riyan/GeoIP2-Enterprise.mmdb;
create temporary function samplefunction as 'com.package.name.App';
select samplefunction('172.73.14.54','country_name','/user/riyan/GeoIP2-Enterprise.mmdb') AS result;

我将GeoIP2-Enterprise.mmdb数据库的位置传递给udf。它在我的本地系统上工作正常。但是当我用它制作jar并在cli中运行时，它会给我一个错误说

FAILED: SemanticException [Error 10014]: Line 1:7 Wrong arguments ''/user/riyan/GeoIP2-Enterprise.mmdb'': org.apache.hadoop.hive.ql.metadata.HiveException: Unable to execute method public static org.apache.hadoop.io.Text com.package.name.App.evaluate(org.apache.hadoop.io.Text,org.apache.hadoop.io.Text,org.apache.hadoop.io.Text)  on object com.package.name.App@1777c0e2 of class com.package.name.App with arguments {172.73.14.54:org.apache.hadoop.io.Text, country_name:org.apache.hadoop.io.Text, /user/riyan/GeoIP.mmdb:org.apache.hadoop.io.Text} of size 3

我还尝试将参数从Text更改为String，这给了我相同的异常。有人能告诉我我做错了什么吗？感谢

修改：添加以下内容

我在hive调试模式下运行它并得到了这个

Answer 1

根据您的回答，您的JAR文件中似乎缺少某些依赖项。你是如何编译包含UDF的项目的？

可能在Hive类路径中遗漏了这个

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.1.4</version>
</dependency>

作为解决方法，您可以尝试使用具有依赖关系的jar进行编译（对于这种情况不是一个好习惯），但至少我们会知道这是否是您的问题

<build>
  <plugins>
    <plugin>
      <artifactId>maven-assembly-plugin</artifactId>
      <configuration>
        <archive>
          <manifest>
          </manifest>
        </archive>
        <descriptorRefs>
          <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
      </configuration>
    </plugin>
  </plugins>
</build>

另一个选项是将此依赖项添加到Hive类路径并再试一次

https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-databind/2.1.4

Answer 2

失败的实际原因是由于以下错误。

引起：java.lang.NoSuchMethodError：com.fasterxml.jackson.databind.node.ObjectNode。（Lcom / fasterxml / jackson / databind / node / JsonNodeFactory; Ljava / util / Map;）V

看起来您可能在类路径中存在冲突版本的jar。

在启动它之前添加-verbose：hs2的类jvm选项，然后查看哪个jar被拾取 - 如果它是旧的或者udf不需要，请删除它。

Hive给出SemanticException [错误10014]：运行我的UDF时
