Why does zookeeper not use my log4j.properties file log directory

Question

In my zookeeper/conf/log4j.properties file I set the zookeeper.log.dir to $HOME/zklogs

When I use zkServer.sh it does not use that directory. Instead it uses the ${Z

Answer 1

Another option to change the file log directory via the ZOO_LOG_DIR environment variable is to create your own zk-server-1/conf/zookeeper-env.sh.

Reading the zookeeper-3.4.6 dist bash scripts(t.i. zkEnv.sh), they source that zookeeper-env.sh file if it exists. Here is it's(my created) content:

export ZOO_HOME=$ZOOKEEPER_PREFIX
echo $ZOO_HOME
export ZOO_LOG_DIR=$ZOO_HOME/logs

I am used to having a PRODUCTNAME_HOME variable, which points to the top installation dir of zookeeper. This top dir seems to be named $ZOOKEEPER_PREFIX by zookeeper dist, which i aliase with $ZOO_HOME und use it for the ZOO_LOG_DIR environment variable.

At the end of this post i spooled out the bash scripts debug info - helps me investigate which environment or local variables plus values are used.

As i see it, the /home/joma/dev/programme/zk-local-ensemble/zk-server-1/bin/../conf dir is on the CLASSPATH, hence the log4j.properties file is eligible for resource loading via java's class-loader for the log4j framework(which is the way log4j is implemented AFAIR).
