Zhijiang Wang reassigned FLINK-5499: ------------------------------------ Assignee: Zhijiang Wang > Try to reuse the resource location of prior execution attempt in allocating > slot > -------------------------------------------------------------------------------- > > Key: FLINK-5499 > URL: https://issues.apache.org/jira/browse/FLINK-5499 > Project: Flink > Issue Type: Improvement > Components: JobManager > Reporter: Zhijiang Wang > Assignee: Zhijiang Wang > > Currently when schedule execution to request to allocate slot from > {{SlotPool}}, the {{TaskManagerLocation}} parameter is empty collection. So > for task fail over scenario, the new execution attempt may be deployed to > different task managers. If setting rockDB as state backend, the performance > is better if the data can be restored from local machine. So we try to reuse > the {{TaskManagerLocation}} of prior execution attempt when allocating slot > from {{SlotPool}}. If the {{TaskManagerLocation}} is empty from prior > executions, the behavior is the same with current status. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
