Description

It would be useful (especially for automated deployments) to have an environment configuration file that could be sourced from the launcher files (e.g. kafka-run-server.sh).

This is how this could look like kafka-env.sh

export KAFKA_JVM_PERFORMANCE_OPTS="-XX:+UseCompressedOops -XX:+DisableExplicitGC -Djava.awt.headless=true \ -XX:+UseG1GC -XX:PermSize=48m -XX:MaxPermSize=48m -XX:MaxGCPauseMillis=20 -XX:InitiatingHeapOccupancyPercent=35' %>" 
export KAFKA_HEAP_OPTS="'-Xmx1G -Xms1G' %>" 
export KAFKA_LOG4J_OPTS="-Dkafka.logs.dir=/var/log/kafka" 

kafka-server-start.sh

 
... 
source $base_dir/config/kafka-env.sh 
... 

This approach is consistent with Hadoop and HBase. However the idea here is to be able to set these values in a single place without having to edit startup scripts.

• is depended upon by: KAFKA-2383 kafka-env should be separated between client and server
• is duplicated by: KAFKA-1234 All kafka-run-class.sh to source in user config file (to set env vars like KAFKA_OPTS)
