At kylin.sh, you can see that you should locate new jar in $KYLIN_HOME/ext
or $KYLIN_HOME/lib
export
HBASE_CLASSPATH_PREFIX=${KYLIN_HOME}/conf:${KYLIN_HOME}/lib/*:${KYLIN_HOME}/ext/*:${HBASE_CLASSPATH_PREFIX}
However, if want to be sure, just add your extra library here:
#additionally add tomcat libs to HBASE_CLASSPATH_PREFIX
export
HBASE_CLASSPATH_PREFIX=${tomcat_root}/bin/bootstrap.jar:${tomcat_root}/bin/tomcat-juli.jar:${tomcat_root}/lib/*:${HBASE_CLASSPATH_PREFIX}:/PATH/TO/YOUR/LIBRARY.jar
