Andrei Shumanski updated FLINK-9453:
------------------------------------
Description:
Flink 1.5.0 incorrectly shows execution statistics and differently from Flink
1.4.1.
I attach screenshots from both versions. It looks like 1.5.0 sums all steps in
operators connected with "forward()". It makes it impossible to understand how
much data was actually consumed.
My test code:
{code:java}
public static void main(String[] args) throws Exception {
StreamExecutionEnvironment env =
StreamExecutionEnvironment.getExecutionEnvironment();
List<Integer> input = new ArrayList<>();
input.add(1);
input.add(2);
input.add(3);
input.add(4);
input.add(5);
DataStream<Integer> stream = env.fromCollection(input).rebalance();
stream.map(i -> i+1).name("incr").forward().map(i ->
i-1).name("decr").forward().print();
env.execute();
}
{code}
