HBASE环境变量的搭建

首先上传解压：

tar -zxvf

配置环境变量：

1.[[email protected] conf]# vi hbase-site.xml

添加：export JAVA_HOME=/root/soft/jdk1.8.0_191

2.在HBASE-site.xml里添加：

<configuration>
<property>
<name>hbase.rootdir</name>
<value>file:///home/testuser/hbase</value>
</property>
<property>
<name>hbase.zookeeper.property.dataDir</name>
<value>/home/testuser/zookeeper</value>
</property>
</configuration>

3。配置环境变量

export HBASE_HOME=/root/soft/hbase-0.98.12.1-hadoop2
export PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin:$ZOOKEEPER_HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$HBASE_HOME/bin

完成之后需要执行：

source /etc/profile

启动：start-hbase.sh

能访问到这个界面就说明成功了。

注意：第一法访问的时候会有一个bug，大概意思是和zookeeper端口号占用了，所以jps一下，将2181端口号先杀死

进入HBASE的建表状态，使用命令：

HBASE shell

hbase创建表：

[[email protected] ~]# hbase shell

HBASE中插入数据用put

如果不知道怎么使用，可以help，或者输入一半，等待程序会提示的。

在HBASE的终端页面，是不能正常删除的，需要将光标移动到前边，倒着删除，或者按住Ctrl键删除

HBASE中插入数据，获取数据的命令：

hbase(main):002:0> put

ERROR: wrong number of arguments (0 for 4)

Here is some help for this command:
Put a cell \'value\' at specified table/row/column and optionally
timestamp coordinates.  To put a cell value into table \'ns1:t1\' or \'t1\'
at row \'r1\' under column \'c1\' marked with the time \'ts1\', do:

  hbase> put \'ns1:t1\', \'r1\', \'c1\', \'value\'
  hbase> put \'t1\', \'r1\', \'c1\', \'value\'
  hbase> put \'t1\', \'r1\', \'c1\', \'value\', ts1
  hbase> put \'t1\', \'r1\', \'c1\', \'value\', {ATTRIBUTES=>{\'mykey\'=>\'myvalue\'}}
  hbase> put \'t1\', \'r1\', \'c1\', \'value\', ts1, {ATTRIBUTES=>{\'mykey\'=>\'myvalue\'}}
  hbase> put \'t1\', \'r1\', \'c1\', \'value\', ts1, {VISIBILITY=>\'PRIVATE|SECRET\'}

The same commands also can be run on a table reference. Suppose you had a reference
t to table \'t1\', the corresponding command would be:

  hbase> t.put \'r1\', \'c1\', \'value\', ts1, {ATTRIBUTES=>{\'mykey\'=>\'myvalue\'}}
