Zhijiang commented on FLINK-13247:
----------------------------------
[~wind_ljy] Glad to hear that you have implemented this feature in your company
and desired to contriute it. I believe it would be a good enhancement to Flink
batch jobs. But I guess most of the committers are pretty busy for the current
release work ATM, so it's better to prepare your detail design and then the
community can judge whether it would be covered in the next release cycle.
> Implement external shuffle service for YARN
> -------------------------------------------

> Key: FLINK-13247
> URL: https://issues.apache.org/jira/browse/FLINK-13247
> Project: Flink
> Issue Type: New Feature
> Components: Runtime / Network
> Reporter: MalcolmSanders
> Priority: Major
>
> Flink batch job users could achieve better cluster utilization and job
> throughput throught external shuffle service because the producers of
> intermedia result partitions can be released once intermedia result
> partitions have been persisted on disks. In
> [FLINK-10653|https://issues.apache.org/jira/browse/FLINK-10653], [~zjwang]
> has introduced pluggable shuffle manager architecture which abstracts the
> process of data transfer between stages from flink runtime as shuffle
> service. I propose to YARN implementation for flink external shuffle service
> since YARN is widely used in various companies.
> The basic idea is as follows:
> (1) Producers write intermedia result partitions to local disks assigned by
> NodeManager;
> (2) Yarn shuffle servers, deployed on each NodeManager as an auxiliary
> service, are acknowledged of intermedia result partition descriptions by
> producers;
> (3) Consumers fetch intermedia result partition from yarn shuffle servers;
