druid.extensions.loadList: 该列表加载的依赖需要放置到/extensions/下面加载的依赖名为文件夹名称
druid.zk.service.host && druid.zk.paths.base: 对于zookeeper的集群主机配置&&在zookeeper中的根路径配置
druid.metadata.storage.*: 对于druid-io的存储介质配置默认为内置的derby数据库,对于配置mysql存储介质的话需要提前将mysql链接jar放置到/lib/目录下
druid.storage.type && druid.storage.storageDirectory: 对于druid-io生成的segments保存位置默认为local && segments保存的文件夹路径(可以为local，hdfs，s3)
druid.indexer.logs.*: 对于druid-io的索引日志配置默认为local(可以为local，hdfs，s3)
druid.selectors.indexing.serviceName: 对于druid-io的索引服务名称
druid.selectors.coordinator.serviceName: 对于druid-io的coordinator服务名称
druid.monitoring.monitors: 对于druid-io的监控指标配置，配置为列表
druid.emitter: 对于druid-io的插件发射器配置比如log日志配置为：

log4j2.xml配置文件

vim conf/druid/_common/log4j2.xml

修改文件内容如下:

<?xml version="1.0" encoding="UTF-8" ?>
<Configuration status="WARN">
    <Appenders>
        <Console name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="%d{ISO8601} %p [%t] %c - %m%n"/>
        </Console>
    </Appenders>
    <Loggers>
        <Root level="info">
            <AppenderRef ref="Console"/>
        </Root>
    </Loggers>
</Configuration>
