Chesnay Schepler reassigned FLINK-6184: --------------------------------------- Assignee: Chesnay Schepler > Buffer metrics can cause NPE > ---------------------------- > > Key: FLINK-6184 > URL: https://issues.apache.org/jira/browse/FLINK-6184 > Project: Flink > Issue Type: Bug > Components: Metrics > Affects Versions: 1.2.0, 1.3.0 > Reporter: Chesnay Schepler > Assignee: Chesnay Schepler > Priority: Blocker > Fix For: 1.3.0 > > > The Buffer metrics defined in the TaskIOMetricGroup are created when a Task > is created. At this time, the bufferPool in the Input gates that the metrics > make use of is still null, leading to possible NPEs. > These metrics should either be created after the required objects are fully > initialized or guard this case with null checks. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
