Summary: Get rid of legacy codes from ClusterClient
Key: FLINK-11146
URL:
https://issues.apache.org/jira/browse/FLINK-11146 Project: Flink
Issue Type: Sub-task
Components: Client, Tests
Affects Versions: 1.8.0
Reporter: TisonKun
Assignee: TisonKun
Fix For: 1.8.0
As [~StephanEwen] mentioned in ML, the client needs big refactoring / cleanup. It should use a proper HTTP client library to help with future authentication mechanisms.
After an investigation I notice that the valid cluster clients are only {{MiniClusterClient}} and {{RestClusterClient}}. Legacy clients, {{StandaloneClusterClient}} and {{YarnClusterClient}}, as well as pre-FLIP-6 codes inside {{ClusterClient}}, should be removed as part of FLINK-10392. With this removal we arrive a clean stage where we can think how to implement a proper HTTP client more comfortably.
1. {{StandaloneClusterClient}} is now depended on by {{LegacyStandaloneClusterDescriptor}} (the removal is tracked by FLINK-10700) and {{FlinkClient}}(part of flink-storm which is decided to be removed FLINK-10571). Also relevant tests need to be ported(or directly removed).
2. The removal of {{YarnClusterClient}} should go along with FLINK-11106 Remove legacy flink-yarn component.
3. Testing classes inheriting from {{ClusterClient}} need to be ported(or directly removed).
4. Get rid of legacy codes inside {{ClusterClient}} it self, such as {{#run(JobGraph, ClassLoader)}}
Besides, what is {{JobClient}} used for? I cannot find valid usages of it.
