Hi Aljoscha,
I am still using Beam on Flink. I have one yarn session running multiple
streaming jobs. The application jar contains some environment specific
run time properties( like ip addresses, rest api end points etc). This
adds overhead in my usecase as we have to deploy this in multiple
environments. I was trying to decouple these properties files from the
uber jar and provide as as either a classpath resource or pass the path
of the file as a system property to the jvm.
So far I noticed following options to achieve this.
* put all properties in a file and use /--classpath/ file://<path to
file> option in /flink run /command . This needs the url to be
accessible from all nodes, something like NFS
* use -D in yarn-session to pass each properties. This will need to
restart the yarn session if a new property gets added.
An ideal solution for me would to provide a local classpath to flink run
command and that gets propagated to other workers automatically :)
Thanks,
Jins

Hi,
Yes, setting the property using -D when creating the session should work to
make it available on all workers. I think after that it cannot be changed since
they JVMs are already running.
If I may ask, what’s your use case for this? Are you still using Beam on Flink
or are you using vanilla Flink with this?
Best,
Aljoscha

Thanks Nico. I am able to pass arguments to the main program, that works, but
not exactly that I was looking for.
I guess to have all worker jvms the same system property, I have to set it at
yarn-session creation time using -D ( haven't tried it yet)
Thanks,

Hi Jins,
I'm not sure whether you can define a system property, but you can include it
in the program arguments of "flink run [OPTIONS] <jar-file> <arguments>"
You may also be able to define system properties but these are probably only
valid in your main() function executed within the flink run script, not any
operators run on other JVM nodes. Have you tried that?

Hello,
I want to set the path of a properties file as System property in my
application(something like -Dkey=value).
Is there a way to set it while submitting a flink job to running YARN
Session? I am using //bin/flink run/ to submit the job to a already
running YARN session.
Thanks,
Jins George
