Yang Wang updated FLINK-10934:
------------------------------
Description:
The Kubernetes do not have a default distributed storage and provide public api
to ship files like Yarn local resource. So we could not ship the user jars and
files on the client side to jobmanager and taskmanager. Also it is not a common
way on Kubernetes. Instead, users usually build their jars and files into the
docker image. So when the jobmanager and taskmanager are launched, the users
jars already existed.
Even if some users do not want to build the jars into the image, they could use
the initContainer to download the jars from the storage(http/s3/etc.).
All in all, the Kubernetes per-job cluster will only support cluster
deploy-mode(now called "application mode").
This ticket depends on FLIP-85(Support cluster deployment). Please reference
the documentation
[FLIP-85|https://cwiki.apache.org/confluence/display/FLINK/FLIP-85+Flink+Application+Mode]
for more information.
