API遠程連接Linux的Zookeeper時報錯

log4j:WARN No appenders could be found for logger (org.apache.zookeeper.ZooKeeper).
log4j:WARN Please initialize the log4j system properly.

測試API連接遠程Linux的Zookeeper時報錯,原因是導入的Maven依賴錯誤

 <dependency>
            <groupId>org.apache.hadoop</groupId>
            <artifactId>zookeeper</artifactId>
            <version>3.3.1</version>
 </dependency>

需要把上面的依賴更換如下依賴

<dependency>
            <groupId>org.apache.zookeeper</groupId>
            <artifactId>zookeeper</artifactId>
            <version>3.4.6</version>
</dependency>
