OK that also explains why it didn't occur for me with the current
release-1.1 branch. ;)
> MetricRegistry life-cycle issues with HA
> ----------------------------------------
>
> Key: FLINK-5179
> URL: https://issues.apache.org/jira/browse/FLINK-5179
> Project: Flink
> Issue Type: Bug
> Components: Metrics
> Affects Versions: 1.2.0
> Reporter: Chesnay Schepler
> Assignee: Chesnay Schepler
> Priority: Blocker
> Fix For: 1.2.0
>
>
> The TaskManager's MetricRegistry is started when the TaskManager is created,
> and shutdown in the TaskManager's postStop method.
> However, the registry is also shutdown within the TaskManager's
> disassociateFromJobManager method; however it is not restarted when the
> connection is re-established.
> Effectively this means that a TaskManager that ever reconnected to a
> JobManager will not report any metrics, since the reporters are shutdown as
> well. Metrics will neither be sent to the WebInterface anymore.
