Summary: Add resource files configuration for Yarn Mode
Issue Type: Improvement
Components: Client, Distributed Coordination
Reporter: Wenlong Lyu
Assignee: Wenlong Lyu
Currently in flink, when we want to setup a resource file to distributed cache,
we need to make the file accessible remotely by a url, which is often difficult
to maintain a service like that. What's more, when we want do add some extra
jar files to job classpath, we need to copy the jar files to blob server when
submitting the jobgraph. In yarn, especially in flip-6, the blob server is not
running yet when we try to start a flink job.
Yarn has a efficient distributed cache implementation for application running
on it, what's more we can be easily share the files stored in hdfs in different
application by distributed cache without extra IO operations.
I suggest to introduce -yfiles, -ylibjars -yarchives options to FlinkYarnCLI to
enable yarn user setup their job resource files by yarn distributed cache. The
options is compatible with what is used in mapreduce, which make it easy to use
for yarn user who generally has experience on using mapreduce.
