解决方法：
1).hbase-env.sh 将 export HBASE_MANAGES_ZK 属性设置为false
export HBASE_MANAGES_ZK=false以下也可以导致这个问题：
1、netstat -antp | fgrep 2181，就知道端口被什么进程占了
2、已经启动ZK，但是HBase并没有使用外部的ZK，导致冲突
2).hbase-site.xml 将 hbase.cluster.distributed 设置为true
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>
再次启动没错了
