Jian He commented on FLINK-12160:
---------------------------------

As the link noted, the  configMap is not suitable for large files like jars, reusing hdfs might be a better idea.

> When deploying flink cluster on Yarn, `yarnShip` cli option could be used to ship user config files and jars. The files are registered as Yarn local resource which is saved on hdfs.
>  
> However, we do not have a default existing dfs. The `ConfigMap` could be used to ship small files. The files will be stored in etcd and then mounted to jobmanager and taskmanager pod so that they could use it as locally.
