Re: Exception with Java Table API example

[Mohamed Nadjib MAMI]

Hello Robert,

I'm not using Scala, no Scala dependency in my pom file.

Thanks

Hi,

the error looks like a mixup of the Scala versions.
Are you adding any scala 2.11 dependencies in your pom?

    Hello,

    Suit to my previous email, apologize, the error was in: /Table
    table = tableEnv.toTable(input);/

    Cheers,
    Mohamed

    Hello all,

    I've just tried the example of Java Table API as-is on the docs
    but I'm getting this exception:

    Line 20 is: /DataSet<WC> result = tableEnv.toSet(filtered, WC.class);

    /What could be the reason firing the exception?/

    /The version used is 0.9-hadoop1-SNAPSHOT/.
