问题补充

1、防火墙均已关闭、root最高权限
2、hadoop启动正常jps查看已启动，通过浏览器访问50070，8088无任何问题
3、Zookeeper启动正常jps查看已启动
4、已删除hbase/lib下所有关于hadoop的jar并将 hadoop/share所有关于Hadoop的jar拷贝到hbase/lib下，并添加aws-java-sdk-core-1.11.和aws-java-sdk-s3-1.11.

版本说明

1、hadoop 2.7.2
2、hbase 1.2.6
3、zookeeper 3.4.2

解决方案：

/usr/local/hadoop/etc/hadoop/ 配置文件中指定主机IP添加如下代码：

      <property>
                <name></name>
                <value>192.168.1.151</value>
       </property>
