Question

我是hive的udf的新手。我已下载“apache-hive-2.1.0-bin”并将项目的构建路径配置为apache-hive-2.1.0-bin\lib（所有广告）。

import org.apache.hadoop.hive.ql.exec.UDF;
import org.apache.hadoop.io.Text;  // <= I am not able to import this package.

public class replace extends UDF {

    private Text result = new Text();

    public Text evaluate(String str, String str1, String str2) {
        String rep = str.replace(str1, str2);
        result.set(rep);
        return result;
    }
}

Answer 1

在lib路径中添加以下内容hadoop-common-2.2.0.jar

将在

中提供

http://central.maven.org/maven2/org/apache/hadoop/hadoop-common/2.2.0/hadoop-common-2.2.0.jar

导入配置单元包时出错
