David Mao created KAFKA-15192: --------------------------------- Summary: Network thread receives exception when updating request metrics Key: KAFKA-15192 URL: https://issues.apache.org/jira/browse/KAFKA-15192 Project: Kafka Issue Type: Bug Components: metrics Reporter: David Mao
We noticed an exception being thrown from the network threads when updating some of the request histograms. Example stack trace: java.util.NoSuchElementException at java.util.concurrent.ConcurrentSkipListMap.firstKey(ConcurrentSkipListMap.java:2064) at com.yammer.metrics.stats.ExponentiallyDecayingSample.update(ExponentiallyDecayingSample.java:102) at com.yammer.metrics.stats.ExponentiallyDecayingSample.update(ExponentiallyDecayingSample.java:81) at com.yammer.metrics.core.Histogram.update(Histogram.java:110) Searching the error I found a similar ticket resolved in Cassandra by updating their dropwizard dependency to pull in [https://github.com/dropwizard/metrics/pull/1436]. https://issues.apache.org/jira/browse/CASSANDRA-15472 Kafka currently still uses yammer metrics, so we would need to take [https://cwiki.apache.org/confluence/display/KAFKA/KIP-510%3A+Metrics+library+upgrade] forward to upgrade to a dropwizard version that fixes this issue. -- This message was sent by Atlassian Jira (v8.20.10#820010)
