[jira] [Created] (FLINK-8781) Try to reschedule failed tasks to
previous allocation
Stefan Richter created FLINK-8781:
-------------------------------------
Summary: Try to reschedule failed tasks to previous allocation
Key: FLINK-8781
URL: https://issues.apache.org/jira/browse/FLINK-8781
Project: Flink
Issue Type: New Feature
Components: Scheduler
Affects Versions: 1.5.0
Reporter: Stefan Richter
Assignee: Stefan Richter
Fix For: 1.5.0
For local recovery, we need to enhance the scheduler so that it always tries to reschedule tasks to their previous location under failures. In particular, tasks that lost their allocation should not take away the previous allocations from other tasks.
