I've created a Maven Java Project to encrypt Hive column using Java UDF as in the below guides:
http://diginbigdata.blogspot.com/2017/01/hive-udf-example-encrypt-decrypt-data_28.html
https://docs.cloudera.com/runtime/7.1.0/using-hiveql/topics/hive_create_udf.html
However when I built the project artifacts and added the JAR file to the configured AUX JAR directory, I receive the following error when I start Beeline:

I also used the solution in this question to exclude signed JARs but still same error.
Here is my Encypt.java
file:
package com.mycompany;
import javax.crypto.Cipher;
import javax.crypto.spec.SecretKeySpec;
import org.apache.commons.codec.binary.Base64;
import org.apache.hadoop.hive.ql.exec.UDF;
public class Encrypt extends UDF {
public String evaluate(String input) {
try {
byte[] password = new String("abcdefghijklmnol").getBytes();
// The password need to be 8, 16, 32 or 64 characters long to be used in AES encryption
Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5Padding");
SecretKeySpec keySpec = new SecretKeySpec(password, "AES");
cipher.init(Cipher.ENCRYPT_MODE, keySpec);
String output = Base64.encodeBase64String(cipher.doFinal(input.getBytes()));
return output;
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
}
And here is my POM.XML

Note: I don't know if it's related or not, but I'm using Kerbros and Sentry in my environment for security. So I use kinit to create a ticket before starting Beeline.
