@chenghao-intel my full code is
```java
import org.apache.hadoop.hive.ql.exec.UDF;
public class hello extends UDF {
public String evaluate(String str) {
try {
return "hello " + str;
} catch (Exception e) {
return null;
}
}
}
```
@adrian-wang ,I also test the `mapjoin_addjar.q` in `spark-sql`.
I got the exception when `CREATE TABLE `
```

But it seems that not the load jar problem.Because when i not run the
```
add jar
${system:maven.local.repository}/org/apache/hive/hcatalog/hive-hcatalog-core/${system:hive.version}/hive-hcatalog-core-${system:hive.version}.jar;
```
I got the follow exception
```
