Hi,

I downloaded Studio 10.0
and installed the streaming extension 0.7.0


But when I open Studio, I get an incompatibility message


If I choose "Ignore", then I'm unable to create a Flink connection.

What are my options to get it to work?

regards
Stephan

    In the meantime I was able to solve this myself by downgrading to Studio 9.10.
    I suspect the reason to be the Java version. Studio 10 uses Java 11, while Studio 9.10 uses Java 8.
    So probably the Streaming Extension 0.7.0 only works with Java 8.

    you are correct that the problem is the change to Java 11. There are plans to upgrade the extension, but this might proof more difficult as this also relies on an upgrade of Spark.

    @jczogalla thanks for the confirmation.

    For the record, I don't currently use the extension.
    I encountered some other mysterious Java errors while trying it out, probably because I made mistakes with the Flink plugin integration, and so I ended up showing it "dry", i.e. only showing the process in the Design view and not actually executing it.
    As the demo I needed this for is over, there is currently no urgent need on my part to fix this.
    Just to let you know I'm not waiting for this ;-)

    OTOH, again for the record, doing even the simplest things in Flink directly (by compiling in Java code) is so appallingly complicated and inefficient that this extension could really make people's lives easier :-)

    regards
    Stephan
