Error in importing hive packages

I am new to hive's udf. I have downloaded "apache-hive-2.1.0-bin" and configured build path of my project to apache-hive-2.1.0-bin\lib (all jars).

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;
    }
}
Solution

  • add the following in lib path hadoop-common-2.2.0.jar

    It will be available in 

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