Guozhang Wang resolved KAFKA-2733. ---------------------------------- Resolution: Fixed Issue resolved by pull request 643 [https://github.com/apache/kafka/pull/643] > Distinguish metric names inside the sensor registry > --------------------------------------------------- > > Key: KAFKA-2733 > URL: https://issues.apache.org/jira/browse/KAFKA-2733 > Project: Kafka > Issue Type: Sub-task > Reporter: Guozhang Wang > Assignee: Guozhang Wang > Fix For: 0.9.1.0 > > > Since stream tasks can share the same StreamingMetrics object, and the > MetricName is distinguishable only by the group name (same for the same type > of states, and for other streaming metrics) and the tags (currently only the > client-ids of the StreamThead), when we have multiple tasks within a single > stream thread, it could lead to IllegalStateException upon trying to registry > the same metric from those tasks. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
