             Summary: Use ClosureCleaner for Join where and equalTo
                 Key: FLINK-4083
                 URL: https://issues.apache.org/jira/browse/FLINK-4083
             Project: Flink
          Issue Type: Bug
    Affects Versions: 1.0.3
            Reporter: Stefan Richter
            Assignee: Stefan Richter
            Priority: Minor


When specifying a key selector in the where or equalTo clause of a Join, the closure cleaner is not used. Same problem as FLINK-4078.

{code}
.join(ds)
	.where(new KeySelector<CustomType, Integer>() {
		@Override
		public Integer getKey(CustomType value) {
			return value.myInt;
		}
	})
	.equalTo(new KeySelector<CustomType, Integer>(){

		@Override
		public Integer getKey(CustomType value) throws Exception {
			return value.myInt;
		}
	});
{code}

The problem is that the KeySelector is an anonymous inner class and as such as a reference to the outer object. Normally, this would be rectified by the closure cleaner but the cleaner is not used in CoGroup.where().
