HighAvailabilityServices
Till Rohrmann created FLINK-6521:
------------------------------------
Summary: Add per job cleanup methods to HighAvailabilityServices
Key: FLINK-6521
URL: https://issues.apache.org/jira/browse/FLINK-6521
Project: Flink
Issue Type: Improvement
Components: Distributed Coordination
Affects Versions: 1.3.0, 1.4.0
Reporter: Till Rohrmann
The {{HighAvailabilityServices}} are used to manage services and persistent state at a single point. This also entails the cleanup of data used for HA. So far the {{HighAvailabilityServices}} can only clean up the data for all stored jobs. In order to support cluster sessions, we have to extend this functionality to selectively delete data for single jobs. This is necessary to keep data for failed jobs and delete data for successfully executed jobs.
