HI
Use below UDF:
Execution Type: All Values Of Context
public void joinList(String[] list, ResultList result, Container container) throws StreamTransformationException{
String join = "";
for (int i = 0 ; i < list.length ; i++){
if (i!= 0) join = join +";"+ list[i];
else join = join + list[i];
}
result.addValue(join);
}Use removeContext before UDF.

Praveen.
