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.
For more on the HBase Shell, see http://hbase.apache.org/book.html
hbase:002:0>
查看命令使用方式以create_namespace为例
hbase:002:0> help 'create_namespace'
Create namespace; pass namespace name,
and optionally a dictionary of namespace configuration.
Examples:hbase> create_namespace 'ns1'hbase> create_namespace 'ns1', {'PROPERTY_NAME'=>'PROPERTY_VALUE'}
hbase:003:0>
上面命令中的list相当于数据库中的show命令。
问题：创建namespace报错！
hbase:002:0> create_namespace 'lwztest'

usage try 'help "create_namespace"'解决方式：
1. 停止hbase集群
2. 在配置文件hbase-site.xml 文件中增加如下配置-->分发到集群其他机器
<property><name>hbase.wal.provider</name><value>filesystem</value>
</property>3. 重启hbase集群

Column specification can be a simple string (name), or a dictionary
(dictionaries are described below in main help output), necessarily
including NAME attribute.

1.2、DML写入读取数据
1、写入数据
在HBase中如果想要写入数据，只能添加结构中最底层的cell。可以手动写入时间戳指定cell的版本，推荐不写默认使用当前的系统时间。
#写入数据
hbase:001:0> put 'lwztest:t_person','1001','info:name','zhangsan'
2024-03-28 23:11:11,460 INFO [RPCClient-NioEventLoopGroup-1-1] Configuration.deprecation (Configuration.java:logDeprecation(1395)) - hbase.client.pause.cqtbe is deprecated. Instead, use hbase.client.pause.server.overloaded
Took 0.2648 seconds
hbase:002:0> put 'lwztest:t_person','1001','info:name','zhangsan'
Took 0.0190 seconds
hbase:003:0> put 'lwztest:t_person','1001','info:name','lisi'
Took 0.0212 seconds
hbase:004:0> put 'lwztest:t_person','1001','info:age','20'
Took 0.0139 seconds
2、读取数据
读取数据的方法有两个：get和scan。
get最大范围是一行数据，也可以进行列的过滤，读取数据的结果为多行cell。
#读取数据
hbase:006:0> get 'lwztest:t_person','1001'
COLUMN CELLinfo:age timestamp=2024-03-28T23:13:30.749, value=20info:name timestamp=2024-03-28T23:13:11.586, value=lisi
1 row(s)
Took 0.1166 seconds
#读取数据
hbase:007:0> scan 'lwztest:t_person'
ROW COLUMN+CELL1001 column=info:age, timestamp=2024-03-28T23:13:30.749, value=201001 column=info:name, timestamp=2024-03-28T23:13:11.586, value=lisi
1 row(s)
Took 0.0394 seconds
3、删除数据
删除数据的方法有两个：delete和deleteall。
delete表示删除一个版本的数据，即为1个cell，不填写版本默认删除最新的一个版本。
deleteall表示删除所有版本的数据，即为当前行当前列的多个cell。（执行命令会标记数据为要删除，不会直接将数据彻底删除，删除数据只在特定时期清理磁盘时进行）
#删除数据
hbase:008:0> delete 'lwztest:t_person','1001','info:name'
Took 0.0254 seconds
hbase:009:0> scan 'lwztest:t_person'
ROW COLUMN+CELL1001 column=info:age, timestamp=2024-03-28T23:13:30.749, value=201001 column=info:name, timestamp=2024-03-28T23:12:52.937, value=zhangsan
1 row(s)
Took 0.0130 seconds
#删除所有版本数据
hbase:010:0> deleteall 'lwztest:t_person','1001','info:name'
Took 0.0107 seconds
hbase:011:0> scan 'lwztest:t_person'
ROW COLUMN+CELL1001 column=info:age, timestamp=2024-03-28T23:13:30.749, value=20
1 row(s)
Took 0.0083 seconds
hbase:012:0>
2、大数据软件启动
由于大数据相关的软件非常多，启动和关闭比较麻烦...自己写一个脚本，直接启动一个脚本把所有软件都起来。按照实际情况编写。
lwz-start.sh
#!/bin/bash
echo "hadoop startup..."
start-all.shecho "zookeeper startup..."
zkServer.sh startssh root@node2 << eeooff
zkServer.sh start
exit
eeooff
ssh root@node3 << eeooff
zkServer.sh start
exit
eeooffecho "hive startup..."
nohup /export/server/hive-3.1.3/bin/hive --service metastore &
nohup /export/server/hive-3.1.3/bin/hive --service hiveserver2 &echo "HBase startup..."
start-hbase.shecho done!lwz-stop.sh
#!/bin/bash
echo "hadoop stop..."
stop-all.shecho "zookeeper stop..."
zkServer.sh stopssh root@node2 << eeooff

exit
eeooff
ssh root@node3 << eeooff
zkServer.sh stop
exit
eeooffecho "hive stop..."echo "HBase stop..."
hbase-daemon.sh stop master
hbase-daemon.sh stop regionserverecho done!3、HBase API
创建一个maven项目，在pom.xml中添加依赖
注意：会报错javax.el包不存在，是一个测试用的依赖，不影响使用
