Liya Fan updated FLINK-13108:
-----------------------------
    Description: 
There are duplicated cast operations in the generated code. For example, to run 
org.apache.flink.table.runtime.batch.sql.join.JoinITCase#testJoin, the 
generated code looks like this:

        {{@Override}}
        {{public void 
processElement(org.apache.flink.streaming.runtime.streamrecord.StreamRecord 
element) throws Exception {}}
          {{org.apache.flink.table.dataformat.BaseRow in1 = 
(org.apache.flink.table.dataformat.BaseRow) 
(org.apache.flink.table.dataformat.BaseRow) 
converter$0.toInternal((org.apache.flink.types.Row) element.getValue());}}
          {{...}}

This issue removes the duplicated type casts.
