------------------------------------
Summary: Try to reuse the resource location of previous execution
attempt when allocate slot
Key: FLINK-5499
URL: https://issues.apache.org/jira/browse/FLINK-5499
Project: Flink
Issue Type: Improvement
Components: JobManager
Reporter: 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.
