I have tried to build and run the pubsub collector but I keep getting the same error.
Seems like I’m missing something. Build is 1.0.1 .
Build steps:
https://github.com/snowplow/snowplow/wiki/Install-the-Scala-Stream-Collector#22-compile-from-source
After git clone, ran this here:
sbt "project pubsub" assembly
Which created .jar in pubsub/target/..../
To run jar file: java -jar snowplow-stream-collector-pubsub-1.0.1.jar --config config.conf
Error:
Exception in thread "main" java.lang.IllegalArgumentException: elementCountThreshold must be either unset or positive
