Till Rohrmann commented on FLINK-13938:
---------------------------------------

How does this issue relate to FLINK-14964 and vice versa? They sound quite 
similar.

> Currently, every time we start a flink cluster, flink lib jars need to be 
> uploaded to hdfs and then register Yarn local resource so that it could be 
> downloaded to jobmanager and all taskmanager container. I think we could have 
> two optimizations.
>  # Use pre-uploaded flink binary to avoid uploading of flink system jars
>  # Use the yarn public cache to eliminate the unnecessary jars downloading 
> and make launching container faster. The public cache could be shared by 
> different applications.
>  
> 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. 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 -ypl argument to specify the shared lib
> {code:java}
> ./bin/flink run -d -m yarn-cluster -p 20 -ypl 
> hdfs://hdpdev/flink/release/flink-1.9.0 
> examples/streaming/WindowJoin.jar{code}
>  
> -ypl, --yarnpreUpload <path>          Upload a copy of flink binary beforehand
>                                                           and specify the 
> path to use public
>                                                           visibility feature 
> of YARN NodeManager
>                                                           localizing
