Hive 给出 SemanticException [错误 10014]: 当 运行 我的 UDF
Hive gives SemanticException [Error 10014]: when Running my UDF
我有一个执行 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);
}
然后我用它制作了一个罐子 运行 配置单元 Cli 中的以下内容
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;
我正在将 GeoIP2-Enterprise.mmdb 数据库的位置传递给 udf。它在我的本地系统上运行良好。但是当我用它制作 jar 并在 cli 中 运行 时，它给了我一个错误说
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，这给了我同样的异常。
有人可以告诉我我做错了什么吗？
谢谢
编辑：添加以下部分
我运行它在配置单元调试模式下得到了这个

根据您的回答，您的 JAR 文件中似乎缺少一些依赖项。您如何编译包含 UDF 的项目？
可能在 Hive 类路径中缺少这个
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.1.4</version>
</dependency>
作为解决方法，您可以尝试使用带有依赖项的 jar 来编译它（对于这种情况不是一个好的做法）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>
另一种选择是将此依赖项添加到 Hive 类路径并重试
https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-databind/2.1.4
失败的实际原因是由于以下错误。
原因：java.lang.NoSuchMethodError：com.fasterxml.jackson.databind.node.ObjectNode.(Lcom/fasterxml/jackson/databind/node/JsonNodeFactory;Ljava/util/Map;)V
看起来您的 class 路径中的 jar 版本可能存在冲突。
在启动它之前向 hs2 添加 -verbose:class jvm 选项，然后查看哪个 jar 被拾取 - 如果 jar 是旧的或 udf 不需要，请将其移除。
