Hbase是一个分布式的实时数据库，他可以基于hadoop的hdfs，S3等分布式存储系统。而且使用zookeeper来通信（查询元数据和获取数据所在位置等功能）
本文的Hbase使用的是hadoop的hdfs和外部的zookeeper。在这里假设你已经搭建好hadoop和zookeeper。
Hbase搭建过程：
1.修改hbase-env.xml文件
export JAVA_HOME=/home/liangjf/app/jdk1.8.0_144 #java安装的根目录export HBASE_MANAGES_ZK=false #false-使用非hbase自带的zookeeper。true-使用hbase自带的zookeeper
2.修改hbase-size.xml文件
hbase.rootdir hdfs://master:9000/hbase hbase.zookeeper.property.clientPort 2181 hbase.cluster.distributed true #指明使用完全分布式 false-单机或伪分布式zookeeper.znode.parent /hbase #注意点1hbase.master hdfs://master:60000 hbase.zookeeper.quorum master,slave1 dfs.datanode.max.xcievers 4096
注意点1：hbase是使用zookeeper来完成其功能的。所以肯定是在zookeeper上创建一个节点来存放其必须的信息。因此在启动hbase客户端的之前，必须在zookeeper上创建一个目录来保存数据。这里是/hbase（实际上这里的名字是随意的，不过为了方便使用了/hbase）。
步骤：
进入zookeeper/bin，执行命令
[liangjf@master bin]$./zkCli.sh[zk: localhost:2181(CONNECTED) 0] ls /[zookeeper][zk: localhost:2181(CONNECTED) 0] create /hbase "123"[zk: localhost:2181(CONNECTED) 0] ls /[zookeeper, hbase]
如果缺少在zookeeper上创建 /hbase这一步（ create /hbase "123" ），在使用的时候会出现以下错误。在这里吐槽一下，网上出现这个错误的解决办法真少。

3.分发整个hbase目录到各节点
scp -r /home/liangjf/app/hbase-0.98.0-hadoop1 liangjf@slave1:/home/liangjf/app
4.启动hbase
进入 /hbase-0.98.0-hadoop1/bin/ 下， ./start-hbase.sh
5.启动hbase客户端
进入 /hbase-0.98.0-hadoop1/bin/ 下， 执行命令 hbase shell ，进入shell客户端。
6.测试
