Unrecognized VM option '+ UseCompressedOops'

Failed to create Java Virtual Machine

JMX is enabled by default

Using config: /home/single/yoga/zookeeper-3.4.5/bin /../ conf / zoo.cfg

Running zookeeper ... START

single @ubuntu: ~ / yoga / kafka_2.8.0-0.8.0 $ bin / kafka-server-start.sh config / server.properties

Unrecognized VM + UseCompressedOops Option

Failed to create Java virtual machine.

Answer 1

Since your virtual machine does not support the "+ UseCompressedOops" parameter. To fix this, remove this option from the kafka configuration, which will help you start both servers (zookeeper and kafka).

1) Go to the Kafka installation directory:

cd kafka_2.8.0-0.8

2) Edit the installer of the kafka script class:

vi bin/kafka-run-class.sh

3) Find the token "KAFKA_JVM_PERFORMANCE_OPTS" and remove the '-XX: + UseCompressedOops' from this line.

ie, before deleting:

KAFKA_JVM_PERFORMANCE_OPTS="-server -XX:+UseCompressedOops -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:+CMSClassUnloadingEnabled -XX:+CMSScavengeBeforeRemark -XX:+DisableExplicitGC -Djava.awt.headless=true"

after removal:

KAFKA_JVM_PERFORMANCE_OPTS="-server -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:+CMSClassUnloadingEnabled -XX:+CMSScavengeBeforeRemark -XX:+DisableExplicitGC -Djava.awt.headless=true"

4) Run both instances of zookeeper and kafka server

./bin/zookeeper-server-start.sh config/zookeeper.properties
./bin/kafka-server-start.sh config/server.properties
