Xintong Song commented on FLINK-16215:
--------------------------------------
I believe the problem of identifying recovered containers in which no TM
process is started should a separate issue. I created another ticket
FLINK-16299 for it.
I also linked this ticket to FLINK-13554 and FLINK-15959, because I believe the
former fixes this issue, and the latter is somehow related to this issue.
> Start redundant TaskExecutor when JM failed
> -------------------------------------------
>
> Key: FLINK-16215
> URL: https://issues.apache.org/jira/browse/FLINK-16215
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Coordination
> Affects Versions: 1.10.0
> Reporter: YufeiLiu
> Priority: Major
>
> TaskExecutor will reconnect to the new ResourceManager leader when JM failed,
> and JobMaster will restart and reschedule job. If job slot request arrive
> earlier than TM registration, RM will start new workers rather than reuse the
> existing TMs.
> It‘s hard to reproduce becasue TM registration usually come first, and
> timeout check will stop redundant TMs.
> But I think it would be better if we make the {{recoverWokerNode}} to
> interface, and put recovered slots in {{pendingSlots}} wait for TM
> reconnection.
