1.1、DDL创建修改表格

1、创建命名空间和表格

2、查看表格

3、修改表

4、删除表

1.2、DML写入读取数据

2、大数据软件启动

一、Apache HBase

1、HBase Shell操作

先启动HBase。再进行下面命令行操作。

1、进入HBase客户端命令行

javascript 复制代码 
[root@node1 hbase-3.0.0]# bin/hbase shell
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/export/server/hadoop-3.3.6/share/hadoop/common/lib/slf4j-reload4j-1.7.36.jar!/org/slf4j/impl/StaticLoggerBinder.class]

SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [org.slf4j.impl.Reload4jLoggerFactory]
HBase Shell
Use "help" to get list of supported commands.
Use "exit" to quit this interactive shell.
For Reference, please visit: http://hbase.apache.org/book.html#shell
Version 3.0.0-beta-1, r119d11c808aefa82d22fef6cd265981506b9dc09, Tue Dec 26 07:40:00 UTC 2023
Took 0.0014 seconds
hbase:001:0>

2、查看帮助命令

能够展示HBase中所有能使用的命令，主要使用的命令有namespace命令空间相关，DDL创建修改表格，DML写入读取数据。

javascript 复制代码

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.
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

javascript 复制代码 
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！

javascript 复制代码 
hbase:002:0> create_namespace 'lwztest'

For 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

javascript 复制代码 
<property>
    <name>hbase.wal.provider</name>
    <value>filesystem</value>
</property>
  1. 重启hbase集群

1.1、DDL创建修改表格

1、创建命名空间和表格

此时操作成功！

Creates a table. Pass a table name, and a set of column family
specifications (at least one), and, optionally, table configuration.
Column specification can be a simple string (name), or a dictionary
(dictionaries are described below in main help output), necessarily
including NAME attribute.
Examples:

Create a table with namespace=ns1 and table qualifier=t1
  hbase> create 'ns1:t1', {NAME => 'f1', VERSIONS => 5}

Create a table with namespace=default and table qualifier=t1
  hbase> create 't1', {NAME => 'f1'}, {NAME => 'f2'}, {NAME => 'f3'}
  hbase> # The above in shorthand would be the following:
  hbase> create 't1', 'f1', 'f2', 'f3'
  hbase> create 't1', {NAME => 'f1', VERSIONS => 1, TTL => 2592000, BLOCKCACHE => true}
  hbase> create 't1', {NAME => 'f1', CONFIGURATION => {'hbase.hstore.blockingStoreFiles' => '10'}}
  hbase> create 't1', {NAME => 'f1', IS_MOB => true, MOB_THRESHOLD => 1000000, MOB_COMPACT_PARTITION_POLICY => 'weekly'}

Table configuration options can be put at the end.
Examples:

  hbase> create 'ns1:t1', 'f1', SPLITS => ['10', '20', '30', '40']
  hbase> create 't1', 'f1', SPLITS => ['10', '20', '30', '40']
  hbase> create 't1', 'f1', SPLITS_FILE => 'splits.txt'
  hbase> create 't1', {NAME => 'f1', VERSIONS => 5}, METADATA => { 'mykey' => 'myvalue' }
  hbase> # Optionally pre-split the table into NUMREGIONS, using
  hbase> # SPLITALGO ("HexStringSplit", "UniformSplit" or classname)
  hbase> create 't1', 'f1', {NUMREGIONS => 15, SPLITALGO => 'HexStringSplit'}
  hbase> create 't1', 'f1', {NUMREGIONS => 15, SPLITALGO => 'HexStringSplit', REGION_REPLICATION => 2, CONFIGURATION => {'hbase.hregion.scan.loadColumnFamiliesOnDemand' => 'true'}}
  hbase> create 't1', 'f1', {SPLIT_ENABLED => false, MERGE_ENABLED => false}
  hbase> create 't1', {NAME => 'f1', DFS_REPLICATION => 1}

You can also keep around a reference to the created table:

  hbase> t1 = create 't1', 'f1'

Which gives you a reference to the table named 't1', on which you can then
call methods.

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。

javascript 复制代码 
#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。

javascript 复制代码 
#读取数据
hbase:006:0> get 'lwztest:t_person','1001'
COLUMN                                          CELL
 info:age                                       timestamp=2024-03-28T23:13:30.749, value=20
 info: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+CELL
 1001                                           column=info:age, timestamp=2024-03-28T23:13:30.749, value=20
 1001                                           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）

javascript 复制代码 
#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+CELL
 1001                                           column=info:age, timestamp=2024-03-28T23:13:30.749, value=20
 1001                                           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+CELL
 1001                                           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

bash 复制代码 
#!/bin/bash
echo "hadoop startup..."
start-all.sh

echo "zookeeper startup..."
zkServer.sh start

ssh root@node2 << eeooff 
zkServer.sh start
exit
eeooff
ssh root@node3 << eeooff 
zkServer.sh start
exit
eeooff

echo "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.sh

echo done!

lwz-stop.sh

bash 复制代码 
#!/bin/bash
echo "hadoop stop..."
stop-all.sh

echo "zookeeper stop..."
zkServer.sh stop

ssh root@node2 << eeooff 
zkServer.sh stop
exit
eeooff
ssh root@node3 << eeooff 
zkServer.sh stop
exit
eeooff

echo "hive stop..."

echo "HBase stop..."
hbase-daemon.sh stop master
hbase-daemon.sh stop regionserver

echo 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

XML 复制代码 
<dependencies>
   <dependency>
       <groupId>org.apache.hbase</groupId>
       <artifactId>hbase-server</artifactId>
       <version>3.0.0-beta-1</version>
       <exclusions>
           <exclusion>
               <groupId>org.glassfish</groupId>
               <artifactId>javax.el</artifactId>
           </exclusion>
       </exclusions>
   </dependency>
   <dependency>
      <groupId>org.apache.hbase</groupId>
      <artifactId>hbase-client</artifactId>
      <version>3.0.0-beta-1</version>
   </dependency>
   <dependency>
      <groupId>org.glassfish</groupId>
      <artifactId>javax.el</artifactId>
      <version>3.0.1-b12</version>
   </dependency>
</dependencies>

Apache HBase(一)

请记住，你当下的结果，由过去决定；你现在的努力，在未来见效；
不断学习才能不断提高！磨炼，不断磨炼自己的技能！学习伴随我们终生！
生如蝼蚁，当立鸿鹄之志，命比纸薄，应有不屈之心。
乾坤未定，你我皆是黑马，若乾坤已定，谁敢说我不能逆转乾坤？
努力吧，机会永远是留给那些有准备的人，否则，机会来了，没有实力，只能眼睁睁地看着机会溜走。
