Hi,
I am trying to create an sql statement that is suppose to return a string and
and integer
Mytable.sql("select mystringfield,myintfield .... )
I am trying to give the typefinormation as a class to the
TypeInformation<Tuple2<String, Long>> tpinf = new TypeHint<Tuple2<String,
Long>>(){}.getTypeInfo();
.toDataStream( , tpinf.getTypeClass() )
However I get the following error shown below.
Can someone give me an example of some working tuples for this case.
Exception in thread "main"
org.apache.flink.api.common.functions.InvalidTypesException: Tuple needs to be
parameterized by using generics.
