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.
> Support to ship user config files on kubernetes
> -----------------------------------------------
>
> Key: FLINK-12160
> URL: https://issues.apache.org/jira/browse/FLINK-12160
> Project: Flink
> Issue Type: Sub-task
> Components: Runtime / Coordination
> Reporter: Yang Wang
> Assignee: Yang Wang
> Priority: Major
>
> 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.
> {code:java}
> -kt,--kubernetesship <arg> Ship files in the specified
> directory
> (t for transfer). Only small
> files(<1MB) could be supported.
