------------------------------------
Summary: Synchronize MetricStore access in the TaskManagersHandler
Key: FLINK-7818
URL: https://issues.apache.org/jira/browse/FLINK-7818
Project: Flink
Issue Type: Bug
Components: Metrics, REST
Affects Versions: 1.3.2, 1.4.0
Reporter: Till Rohrmann
Assignee: Till Rohrmann
The {{TaskManagersHandler}} accesses the {{MetricStore}} when details for a
single {{TaskManager}} are requested. The access is not synchronized which can
be problematic because the {{MetricStore}} is not thread safe.
I propose to add synchronization.
