Summary: Unable to use newer JVM memory settings as Xmx overrides Key: ZOOKEEPER-4391 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-4391 Project: ZooKeeper Issue Type: Improvement Components: scripts Reporter: Daniel Kimsey The Zookeeper environment initialization scripts [forcibly|https://gitbox.apache.org/repos/asf?p=zookeeper.git;a=blob;f=bin/zkEnv.sh;h=8d93a50c7c0cedee6a23746362e7b6fff96ad61c;hb=refs/heads/master#l144] set an {{Xmx}} setting. This is an issue for more flexible configuration JVM memory options like ({{MaxRAMPercentage}} and {{InitialRAMPercentage}}) as Xmx overrides them. Ideally, if SERVER_JVMFLAGS/CLIENT_JVMFLAGS are set, we should not attempt to modify them as the operator has decided what flags to set. However, this would be a behavior change, I don't know if the project is interested/willing to do that. Alternatively, we add a flag to disable the default (current) behavior. {code:sh} # default heap for zookeeper server if [ "$ZK_SKIP_XMX" != "yes" ]; ZK_SERVER_HEAP="${ZK_SERVER_HEAP:-1000}" export SERVER_JVMFLAGS="-Xmx${ZK_SERVER_HEAP}m $SERVER_JVMFLAGS" fi {code} Repeat for CLIENT_JVMFLAGS.
