錯誤截圖 ：

解決方法： 

1).hbase-env.sh 將 export HBASE_MANAGES_ZK 屬性設定為false 

export HBASE_MANAGES_ZK=false

以下也可以導致這個問題：

1、netstat -antp | fgrep 2181，就知道埠被什麼程序佔了

2、已經啟動ZK，但是HBase並沒有使用外部的ZK，導致衝突

2).hbase-site.xml 將 hbase.cluster.distributed 設定為true

<property>
<name>hbase.cluster.distributed</name> 
<value>true</value>
</property>
 

再次啟動沒錯了

 1、Hbase架構及工作原理、資料及物理模型、Hbase優化

 2、Hbase常用優化、Hbae效能優化、Hbase優化經驗總結

 3、Hbase錯誤總結：Hbase未正常關閉啟動報錯

4、Hbase錯誤總結：Hbase連線不上Zookeeper
