Manikumar Reddy commented on KAFKA-1566:
----------------------------------------
Also, it will be good , if we add all possible environment variables to
kafka-env.sh (in comments)
{code}
#export LOG_DIR="/tmp/logs/
#export KAFKA_JMX_OPTS="-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.authenticate=false"
#export JMX_PORT="9999"
#export KAFKA_HEAP_OPTS="-Xmx300M"
#export KAFKA_JVM_PERFORMANCE_OPTS="-server -XX:+UseParNewGC
-XX:+UseConcMarkSweepGC -Djava.awt.headless=true"
#export KAFKA_GC_LOG_OPTS="-Xloggc:$LOG_DIR/mygc.txt -XX:+PrintGCDetails"
{code}

> 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
> {code}
> 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"
> {code}
> kafka-server-start.sh
> {code}
> ...
> source $base_dir/config/kafka-env.sh
> ...
> {code}
> 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.
