Hi,
Nope, that is the only uid in the whole project. The “userRawDataStream" comes
from a splitter:
public static class Splitter implements OutputSelector<EventRaw>{
@Override
public Iterable<String> select(EventRaw value) {
List<String> output = new ArrayList<>();
output.add(value.type);
return output;
}
}
Any ideas how to get better debug messages?

Hello,
was a uid set on "userRawDataStream", or any of it's parent transformations?

Hi,
I am trying to set uids. I keep getting this (Flink.1.2):
Exception in thread "main" java.lang.IllegalArgumentException: Hash collision
on user-specified ID. Most likely cause is a non-unique ID. Please check that
all IDs specified via `uid(String)` are unique.
Here is the code snippet.
public DataStream<UserAction> processUserActions(DataStream<UserRaw>
userRawDataStream, Time duration, Sonar.ReportSpan span) {
return userRawDataStream.map(userRaw->new
UserActionValue(userRaw)).startNewChain().uid("111111")
.keyBy("userRaw.eventRaw.env_key","userRaw.eventRaw.tag","userRaw.eventRaw."+span.name(),"userRaw.type")
.window(GlobalWindows.create())
.trigger(new TimedTrigger(duration))
.sum("count")//.startNewChain().uid("22222222")
.map(userActionsCount->new
UserAction(userActionsCount,span));//.startNewChain().uid("33333333");
}
I made sure that they are unique and even with one uid, the error is there. I
guess there is an easy fix, but I cannot see it.
