Hi,
I want to add the uid for my Kafka sink in such a way that I can still use
the existing savepoint. The problem I'm having is that I cannot set the uid
hash. If I try something like this:
```
output.sinkTo(outputSink).setUidHash("xyzbbbbbbbbbbbbbbbbbbbbbbbbbbbbb");
```
I get the following error:
```
Exception in thread "main" java.lang.UnsupportedOperationException: Cannot
set a custom UID hash on a non-legacy sink
at
org.apache.flink.streaming.api.datastream.DataStreamSink.setUidHash(DataStreamSink.java:163)
```
How can one set the operator id directly then for new (non-legacy) sinks?
Kind regards,
Salva
