---------------------------------------
Summary: 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: 1.1.3
Reporter: Chesnay Schepler
Assignee: Chesnay Schepler
Priority: Blocker
Fix For: 1.2.0, 1.1.4
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.
