---------------------------------------
Summary: IT test for fine-grained recovery (task executor failures)
Key: FLINK-13169
URL: https://issues.apache.org/jira/browse/FLINK-13169
Project: Flink
Issue Type: Sub-task
Components: Runtime / Coordination
Reporter: Andrey Zagrebin
Assignee: Andrey Zagrebin
Fix For: 1.9.0
The BatchFineGrainedRecoveryITCase can be extended with an additional test
failure strategy which abruptly shuts down the task executor. This leads to the
loss of all previously completed and the in-progress mapper result partitions.
The fail-over strategy should subsequently restart the current in-progress
mapper and all previous mappers because the previous result is unavailable.
When the source is recomputed, all mappers has to be restarted again to
recalculate their lost results.
