org.apache.hadoop.hive.ql.udf.ptf.TableFunctionResolver.initializeOutputOI()
This method is invoked during runtime(during deserialization of theQueryDef). At this point the TableFunction can assume that the {@link ExprNodeDesc Expression Nodes}exist for all the Def (ArgDef, ColumnDef, WindowDef..). It is the responsibility of the TableFunction to construct the {@link ExprNodeEvaluator evaluators} and setup the OI. @param tblFuncDef @param ptfDesc @throws HiveException

    inpShape = def.getRawInputShape();


    /*
     * 4. give Evaluator chance to setup for Output execution; setup Output shape.
