Gwen Shapira created KAFKA-2049: ----------------------------------- Summary: Add thread that detects JVM pauses Key: KAFKA-2049 URL: https://issues.apache.org/jira/browse/KAFKA-2049 Project: Kafka Issue Type: Improvement Reporter: Gwen Shapira Assignee: Gwen Shapira
Long JVM pauses can cause Kafka malfunctions (especially when interacting with ZK) that can be challenging to debug. I propose implementing HADOOP-9618 in Kafka: Add a simple thread which loops on 1-second sleeps, and if the sleep ever takes significantly longer than 1 second, log a WARN. This will make GC pauses (and other pauses) obvious in logs. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
