Chesnay Schepler created FLINK-4054: ---------------------------------------
Summary: Inconsistent Reporter synchronization within report() Key: FLINK-4054 URL: https://issues.apache.org/jira/browse/FLINK-4054 Project: Flink Issue Type: Improvement Components: Metrics Affects Versions: 1.1.0 Reporter: Chesnay Schepler Priority: Critical Fix For: 1.1.0 There are currently 2 distinct approaches to how added/removed metrics are handled while a Reporter is in report(). The StatsDReporter simply catches possible exceptions (ConcurrentModificationException/NoSuchElementException) and reports the next time, while all other reporters access the metrics in a synchronized block. We should have a clear line as to which approach people should use. Whether FLINK-3998 is a valid issue depends on this decision. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
