搭建hbase伪分布

1.下载

http://archive.cloudera.com/cdh5/cdh/5/hbase-1.2.0-cdh5.7.5.tar.gz

2.解压
tar -zxvf hbase-1.2.0-cdh5.7.5.tar.gz

3.修改$HBASE_HOME/conf/hbase-env.sh

export JAVA_HOME=/opt/soft/jdk1.8.0_40

export HBASE_CLASSPATH=/opt/soft/hadoop-2.6.0-cdh5.7.0/etc/hadoop

export HBASE_PID_DIR=/opt/soft/hbase-1.2.0-cdh5.7.5/hbase/pids

export HBASE_MANAGES_ZK=true

4.修改$HBASE_HOME/conf/hbase-site.xml

<property>
<name>hbase.rootdir</name>
<value>hdfs://hadoop01:8020/hbase</value>
</property>
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>
<property>
<name>hbase.tmp.dir</name>
<value>/opt/soft/hbase-1.2.0-cdh5.7.5/hbase/tmp</value>
</property>

5.修改regionservers(将主机名添加进去，每行一个)

hadoop01

6.修改环境变量(添加HBASE_HOME和PATH)

export HBASE_HOME=/opt/soft/hbase-1.2.0-cdh5.7.5
export PATH=$HBASE_HOME/bin:$PATH

7.启动hbase(打开hbaseUI界面进行查看，默认端口号是60010)

在启动hbase之前，首先启动hdfs的进程，因为hbase的底层存储依赖hdfs

# bin/start-hbase.sh  

8.停止hbase

# bin/stop-hbase.sh 

9.hbase基本的命令使用:

# cd bin/

# ./hbase

Usage: hbase [<options>] <command> [<args>]
Options:
  --config DIR    Configuration direction to use. Default: ./conf
  --hosts HOSTS   Override the list in 'regionservers' file

简单使用一下命令：# ./hbase shell

hbase(main):004:0> help
HBase Shell, version 1.2.0-cdh5.7.5, rUnknown, Wed Nov  2 12:02:54 PDT 2016

Commands are grouped. Type 'help "COMMAND_GROUP"', (e.g. 'help "general"') for help on a command group.

SHELL USAGE:
Quote all names in HBase Shell such as table and column names.  Commas delimit
command parameters.  Type <RETURN> after entering a command to run it.
Dictionaries of configuration used in the creation and alteration of tables are
Ruby Hashes. They look like this:


  {'key1' => 'value1', 'key2' => 'value2', ...}


and are opened and closed with curley-braces.  Key/values are delimited by the
'=>' character combination.  Usually keys are predefined constants such as
NAME, VERSIONS, COMPRESSION, etc.  Constants do not need to be quoted.  Type
'Object.constants' to see a (messy) list of all constants in the environment.


If you are using binary keys or values and need to enter them in the shell, use
double-quote'd hexadecimal representation. For example:


  hbase> get 't1', "key\x03\x3f\xcd"
  hbase> get 't1', "key\003\023\011"
  hbase> put 't1', "test\xef\xff", 'f1:', "\x01\x33\x40"


The HBase shell is the (J)Ruby IRB with the above HBase-specific commands added.

创建一张表：

create 'user','info'

查看有多少张表：

list

描述表：

describe 'user'

插入数据：

put 'user','10001','info:name','zhangsan' 

put 'user','10001','info:age','25'

数据查询的方式：

* 依据rowkey查询，最快的(查询结果按照rowkey排序)

get 'user','10001' 

* 范围查询

scan range
scan 'user',{COLUMNS=>['info:name','info:age']}  -->过滤数据

* 全表扫描

scan  'user'

删除数据：

delete 'user','10001','info:name'   

删除所有数据：

deleteall 'user','10001'
