本文详细介绍了如何在Mint系统中安装并配置VirtualBox，随后通过root权限安装Hadoop、Zookeeper和HBase，并进行相应的配置，包括HDFS、HBase和Zookeeper的初始化设置，最终实现系统的搭建。

由于mint安装virtualbox中,为了方便操作直接用root安装了.

# Be sure to read the maintenance section of the

启动:
1 hdfs
hadoop namenode -format
start-dfs.sh
2 zookeeper
zkServer.sh start
3 hbase
start-hbase.sh
4 查看进程
