Quickstart issue

[Philippe Rigaux]

Hello,

Just to inform you that I have not been able to use the quickstart method. Everything works well, but the jar file produced by maven is empty (it only contain a manifest file).

Unclear how this is related to the assembly option. I created a regular

java project and it is ok, but using the quickstart would be pleasant. Let me know if you need more info (well I did  not do much except trying
to fix the pom.xml).

Cheers

Hi,

thank you for reporting the issue. The files created by the quickstart.sh script are in the "org.apache.flink" namespace, which we filter out (to avoid adding all the flink dependencies into the fat jar).

If you relocate the files to another package, it should work.

Sorry for the inconvenience. I'll provide a fix for the issue so that its fixed for the 0.8 release.

Thanks Robert. I misunderstand something, probably. I still get the same error.

Hi Philippe,

maybe you didn't update the entries for the MANIFEST.MF file. (It's my fault, I forgot that you have to change this as well)
I think its a property in the pom.xml. (You'll find it by the class name).

There is another possible workaround that doesn't require you to re-build the jar package.

The /flink/run command allows you to specify the classname you wish to run, using the "-c" flag.

On a side note: if you run an example using java -jar, it will not submit the example to the Flink cluster but run it using a LocalExecutor in one JVM.

Let me know if you need further help.

Best,

Robert
