In the log, I can see that:
First exception is a warning, not sure if it is important.
Second one seems to be the one. It tries to find the file "-yn" ???

Objet : 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?

Hi Florian,
You write that Flink 1.4.2 works but what version is not working for you?
Best,

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

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 ?
