[jira] [Created] (FLINK-9827) ResourceManager may receive outdate report of slots status from task manager
shuai.xu created FLINK-9827:
Summary: ResourceManager may receive outdate report of slots status from task manager
Issue Type: Bug
Components: Cluster Management
Affects Versions: 1.5.0
TaskExecutor will report its slot status to resource manager in heartbeat, but this is in a different thread with the main rpc thread. So it may happen that rm request a slot from task executor but then receive a heartbeat saying the slot not assigned. This will cause the slot be freed and assigned again.
