How to set the class path and java heap size
David Nickerson 2012-08-29, 21:15
I'm starting a ZooKeeper server on Linux by running the following script:
#!/bin/bash
export CLASSPATH="~/zookeeper-3.3.6/conf/log4j.properties"
export JVMFLAGS="-Xmx1500m"
~/zookeeper-3.3.6/bin/zkServer.sh start
It seems to work fine, but is this properly adding the log4j.properties
file to the classpath and setting the java heap size?

Add a file named "java.env" to the "conf" directory. But your Java settings there.

This "java.env" configuration seems to be non-standard
and ZooKeeper-specific. I also can't find it anywhere in the ZooKeeper
documentation. Would "java.env" look like this?
export CLASSPATH="~/zookeeper-3.3.6/conf/log4j.properties"
export JVMFLAGS="-Xmx1500m"

i.e.
-Xmx1G -Xms500m

zkEnv.sh has the following lines:
if [ -e "$ZOOCFGDIR/java.env" ]
then
. "$ZOOCFGDIR/java.env"
fi
It is my understanding that this says, "If java.env exists in the conf
directory, then execute it". If this is so, then java.env needs to be an
executable shell script.

OK - you're correct - I was thinking of something else. I apologize for the misinformation.
