> By default, the LocalResourceVisibility is APPLICATION, so they will be
> downloaded only once and shared for all taskmanager containers of a same
> application in the same node. However, different applications will have to
> download all jars every time, including the flink-dist.jar. I think we could
> use the yarn public cache to eliminate the unnecessary jars downloading and
> make launching container faster.
>
> How to use the shared lib feature?
> # Upload a copy of flink release binary to hdfs.
> # Use the -ysl argument to specify the shared lib
> {code:java}
> ./bin/flink run -d -m yarn-cluster -p 20 -ysl
> hdfs:///flink/release/flink-1.9.0/lib examples/streaming/WindowJoin.jar{code}
>
> -ysl, --yarnsharedLib <path> Upload a copy of flink lib beforehand
> and specify the
> path to use public
> visibility feature
> of YARN NodeManager
> localizing
> resources.
