Tao Wang created FLINK-6341:
-------------------------------
Summary: JobManager can go to definite message sending loop when
TaskManager registered
Key: FLINK-6341
URL: https://issues.apache.org/jira/browse/FLINK-6341
Project: Flink
Issue Type: Bug
Components: JobManager
Reporter: Tao Wang
Assignee: Tao Wang
When TaskManager register to JobManager, JM will send a "NotifyResourceStarted"
message to kick off Resource Manager, then trigger a reconnection to resource
manager through sending a "TriggerRegistrationAtJobManager".
When the ref of resource manager in JobManager is not None and the reconnection
is to same resource manager, JobManager will go to a infinite message sending
loop which will always sending himself a "ReconnectResourceManager" every 2
seconds.
We have already observed that phonomenon. More details, check how JobManager
handles `ReconnectResourceManager`.
