It is totally different using the BlobStore. For clusters with BlobStore,
DistributedCache may be enough. I think in the future, we can support
DistributedCache with BlobStore in the future, and support external BlobStore
structure which already run on existed framework, like yarn distributed cache
in the future

> Key: FLINK-5815
> URL: https://issues.apache.org/jira/browse/FLINK-5815
> Project: Flink
> Issue Type: Improvement
> Components: Client, YARN
> Affects Versions: 1.3.0
> 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.
