RE: Could not build the program from JAR file.

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" ???

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,
Gary

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 ?
