------------------------------
Summary: change default JVM options in kafka-run-class.sh
Key: KAFKA-2514
URL: https://issues.apache.org/jira/browse/KAFKA-2514
Project: Kafka
Issue Type: Improvement
Components: config
Reporter: Jun Rao
Priority: Blocker
Fix For: 0.8.3
Since we have stopped supporting java 6, we should improve the default jvm
options. For example, we should probably change the following to G1 collectors.
if [ -z "$KAFKA_JVM_PERFORMANCE_OPTS" ]; then
KAFKA_JVM_PERFORMANCE_OPTS="-server -XX:+UseParNewGC -XX:+UseConcMarkSweepGC
-XX:+CMSClassUnloadingEnabled -XX:+CMSScavengeBeforeRemark
-XX:+DisableExplicitGC -Djava.awt.headless=true"
fi
