Subject [GitHub] flink pull request #2159: [FLINK-3942] [tableAPI] Add support for INTERSECT

    [FLINK-3942] [tableAPI] Add support for INTERSECT

    Internally, I translate INTERSECT into a Join on all fields and then a distinct for removing
duplicate records. 
    
    As Calcite SQL Parser doesn't support `INTERSECT ALL` , so I didn't add `intersectAll()`
function to `Table`.
    
    I can add the corresponding documents if needed.
