-------------------------------------

             Summary: External UDF cannot deinitialize 
                 Key: ASTERIXDB-2175
                 URL: https://issues.apache.org/jira/browse/ASTERIXDB-2175
             Project: Apache AsterixDB
          Issue Type: Bug
            Reporter: Xikui Wang


Due to the nature of IScalarEvaluator, which is the interface that external UDF 
implements, the evaluators cannot be deinitialized/closed when the job is 
finished. One option would be adding an close/deinitialize method to the 
interface and have it called when the close method is called. This needs a 
wider discussion...
