-----------------------------------
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.
