What about this SO question - I think it could be a good idea to add some additional validation between nodes configurations at node's start. Because, if the root of the problem was found correctly, then it means that nodes were started with inconsistent configurations. What do you think?
Sure, here are a few questions: https://stackoverflow.com/questions/45911616/datastreamer-does-not-work-well/4597234 - it doesn't relate to DataStreamer, looks like since version 2.1(or earlier) we have problems with old versions of Java7. I've seen also at least two same questions on the user list. I've created issue for that: https://issues.apache.org/jira/browse/IGNITE-6248 https://stackoverflow.com/questions/45034975/apache-ignite-data-streamer/45035436 - As he said at the end, I think he didn't properly understand how DataStreamer should work http://apache-ignite-users.70518.x6.nabble.com/Failing-DataStreamer-beacuse-of-minor-version-change-td12142.html - for this issue, we already have an improvement too: https://issues.apache.org/jira/browse/IGNITE-5195 Evgenii 2017-09-03 18:13 GMT+03:00 Dmitriy Setrakyan <dsetrak...@apache.org>: > In that case we either provide bad configuration or bad error messages. > Could we provide a better error message for this SO issue? > > Evgenii, can I please ask you to provide links to all the data streamer > questions you looked at here?
