目录

一、Apache HBase

1、HBase Shell操作

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

1、写入数据

2、读取数据

3、删除数据

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

[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: Found binding in [jar:file:/export/server/hbase-3.0.0/lib/client-facing-thirdparty/log4j-slf4j-impl-2.17.2.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

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。

Type 'help "COMMAND"', (e.g. 'help "get"' -- the quotes are necessary) for help on a specific command.
Commands are grouped.

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'

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

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=t1hbase> create 'ns1:t1', {NAME => 'f1', VERSIONS => 5}Create a table with namespace=default and table qualifier=t1hbase> 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.

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。

#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 
zkServer.sh stop
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

<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。
