Description

zkcli uses the log4j configuration in the local directory:

sdir="`dirname \"$0\"`"

PATH=$JAVA_HOME/bin:$PATH $JVM -Dlog4j.configuration=file:$sdir/log4j.properties -classpath "$sdir/../../solr-webapp/webapp/WEB-INF/lib/*:$sdir/../../lib/ext/*" org.apache.solr.cloud.ZkCLI ${1+"$@"}

which is a reasonable default, but often people want to use a "global" log4j configuration. For example, one may define a log4j configuration that writes to an external log directory and want to point to this rather than copying it to each source checkout.
