Re: Could not build the program from JAR file.

Hi Florian,

The error message is because of a FileNotFoundException, see here[1]. Is there any more information about the exception. Do you make sure the jar exist?

Thanks, vino.

Hi Florian,

You write that Flink 1.4.2 works but what version is not working for you?

Hi all,

I'm trying to run the wordCount example on my YARN cluster and this is not working.. I get the error message specified in title: Could not build the program from JAR file.

I also have the same problem with a custom JAR...

With Flink 1.4.2, I have no problem at all. Both the WordCount example and my custom JAR are working...

What do I do wrong ?
