Subject RE: Could not build the program from JAR file.
Date Tue, 07 Aug 2018 07:22:49 GMT
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?

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.

> $ ./bin/flink run -m yarn-cluster -yn 4 -yjm 1024 -ytm 4096 ./examples/batch/WordCount.jar
> Setting HADOOP_CONF_DIR=/etc/hadoop/conf because no HADOOP_CONF_DIR was set.
> Could not build the program from JAR file.

> Use the help option (-h or --help) to get help on the command.

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

What do I do wrong ?
