Xintong Song commented on FLINK-18760: -------------------------------------- Offline discussed with [~Jiangang], and he's willing to work on this ticket as a follow-up of FLINK-18625. Thanks [~Jiangang]. > Redundant task managers should be released when there's no job running in > session cluster > ----------------------------------------------------------------------------------------- > > Key: FLINK-18760 > URL: https://issues.apache.org/jira/browse/FLINK-18760 > Project: Flink > Issue Type: Improvement > Components: Runtime / Coordination > Affects Versions: 1.12.0 > Reporter: Xintong Song > Assignee: Liu > Priority: Major > Fix For: 1.12.0 > > > In FLINK-18625, we introduced redundant task managers, as backup resources > for speeding up job recovery in cases of task manager lost. > For a session cluster, when there's no job running, it would be better to not > keep such redundant resources. Currently, Flink session cluster will not > request redundant task managers until a job is submitted, but it also will > not release redundant task managers after all jobs terminated. > This ticket proposes to check and release task managers if there are > redundant task managers only. -- This message was sent by Atlassian Jira (v8.3.4#803005)
