Is the method called multiple times with different input sets?
Does the issue occur regardless of which uid you set?

Hi,
Nope, that is the only uid in the whole project. The
“userRawDataStream" comes from a splitter:
public static class Splitterimplements 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.
