I'm getting the following error when compiling jar

Question

The following is my java code:

package com.hive.udf;

import org.apache.hadoop.hive.ql.exec.UDF;

import org.apache.hadoop.io.text;

public final class MyUpper extends UDF{

public Text evaluate(final Text s) {

if(s == null) {return null;}

return new text(s.toString().toUpperCase());

}

}

How to resolve this issue?

Answer 1

Try using the following command to fix this issue:

javac -cp 'hadoop classpath':”/usr/lib/hadoop/*:/usr/lib/hive/lib/*” com/hive/udf/MyUpper.java

Using this will direct you to the hadoop classpath directory and your error will be resolved as the package would be accessible.
