《CentOS 6.3 下 Hadoop 伪分布式平台搭建 http://www.linuxidc.com/Linux/2016-11/136789.htm》后就开始搭建 hbase 伪分布式平台了。有了 hadoop 环境,搭建 hbase 就变得很容易了。

一、Hbase 安装

1、从官网下载最新版本 Hbase 安装包 1.2.3,为了省去编译安装环节,我直接下载了 hbase-1.2.3-bin.tar.gz,解压即可使用。(如果此链接下载速度过慢可更换官网其他下载链接)

[hadoop@master tar]$ tar -xzf hbase-1.2.3-bin.tar.gz 
[hadoop@master tar]$ mv hbase-1.2.3 /usr/local/hadoop/hbase
[hadoop@master tar]$ cd /usr/local/hadoop/hbase/
[hadoop@master hbase]$ ./bin/hbase version
HBase 1.2.3
Source code repository git://kalashnikov.att.net/Users/stack/checkouts/hbase.git.commit revision=bd63744624a26dc3350137b564fe746df7a721a4
Compiled by stack on Mon Aug 29 15:13:42 PDT 2016
From source with checksum 0ca49367ef6c3a680888bbc4f1485d18

运行上面命令得到正常输出即表示安装成功,然后配置环境变量

2、配置环境变量

修改~/.bashrc 在 PATH 后面增加

:$HADOOP_HOME/hbase/bin

则~/.bashrc 文件内容如下

export HADOOP_HOME=/usr/local/hadoop
export HADOOP_INSTALL=$HADOOP_HOME
export HADOOP_MAPRED_HOME=$HADOOP_HOME
export HADOOP_COMMON_HOME=$HADOOP_HOME
export HADOOP_HDFS_HOME=$HADOOP_HOME
export YARN_HOME=$HADOOP_HOME
export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native
export PATH=$PATH:$HADOOP_HOME/sbin:$HADOOP_HOME/bin:$HADOOP_HOME/hbase/bin
export HADOOP_CONF_DIR=$HADOOP_HOME/etc/hadoop
 
[hadoop@master hadoop]$ source ~/.bashrc

二、Hbase 单机模式

1、修改配置文件 hbase/conf/hbase-env.sh 

# export JAVA_HOME=/usr/java/jdk1.6.0/   修改为
export JAVA_HOME=/usr/local/java/

#export HBASE_MANAGES_ZK=true   修改为
export HBASE_MANAGES_ZK=true

# 添加下面一行
export HBASE_SSH_OPTS="-p 322"

2、修改配置文件 hbase/conf/hbase-site.xml

<configuration>     
    <property>
        <name>hbase.rootdir</name>
        <value>file:/usr/local/hadoop/tmp/hbase/hbase-tmp</value>
    </property>
</configuration>

3、启动 Hbase

[hadoop@master hbase]$ start-hbase.sh 
starting master, logging to /usr/local/hadoop/hbase/bin/../logs/hbase-hadoop-master-master.out
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option PermSize=128m; support was removed in 8.0
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=128m; support was removed in 8.0

jps 下多了一个 HMaster 进程

[hadoop@master hbase]$ jps
12178 ResourceManager
11540 NameNode
4277 Jps
11943 SecondaryNameNode
12312 NodeManager
11707 DataNode
3933 HMaster

4、使用 Hbase shell

[hadoop@master hbase]$ hbase shell
2016-11-07 10:11:02,187 WARN  [main] util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/usr/local/hadoop/hbase/lib/slf4j-log4j12-1.7.5.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/usr/local/hadoop/share/hadoop/common/lib/slf4j-log4j12-1.7.10.jar!/org/slf4j/impl/StaticLoggerBinder.class]

SLF4J: Actual binding is of type [org.slf4j.impl.Log4jLoggerFactory]
HBase Shell; enter 'help<RETURN>' for list of supported commands.
Type "exit<RETURN>" to leave the HBase Shell
Version 1.2.3, rbd63744624a26dc3350137b564fe746df7a721a4, Mon Aug 29 15:13:42 PDT 2016

hbase(main):001:0> status
1 active master, 0 backup masters, 1 servers, 0 dead, 2.0000 average load

hbase(main):002:0> exit

未启动 Hbase 直接使用 Hbase Shell 会报错

5、停止 Hbase

[hadoop@master hbase]$ stop-hbase.sh 
stopping hbase......................

三、Hbase 伪分布式

伪分布式和单机模式的区别主要是配置文件的不同

1、修改配置文件  hbase/conf/hbase-env.sh 

# export JAVA_HOME=/usr/java/jdk1.6.0/   修改为
export JAVA_HOME=/usr/local/java/

# export HBASE_MANAGES_ZK=true   修改为
export HBASE_MANAGES_ZK=true

# export HBASE_CLASSPATH=   修改为
export HBASE_CLASSPATH=/usr/local/hadoop/etc/hadoop/

# 添加下面一行
export HBASE_SSH_OPTS="-p 322"

zookeeper 使用 Hbase 自带的即可,分布式才有必要开启独立的

2、修改配置文件 hbase/conf/hbase-site.xml

<configuration>
    <property>
        <name>hbase.rootdir</name>
        <value>hdfs://10.1.2.108:9000/hbase</value>
    </property>
    <property>
        <name>hbase.cluster.distributed</name>
        <value>true</value>
    </property>
</configuration>

注意这里的 hbase.rootdir 设置为 hdfs 的存储路径前提是 hadoop 平台是伪分布式,只有一个 NameNode

3、启动 Hbase

[hadoop@master hbase]$ start-hbase.sh 
localhost: starting zookeeper, logging to /usr/local/hadoop/hbase/bin/../logs/hbase-hadoop-zookeeper-master.out
master running as process 3933. Stop it first.
starting regionserver, logging to /usr/local/hadoop/hbase/bin/../logs/hbase-hadoop-1-regionserver-master.out

jps 查看进程多了 HMaster 和 HRegionServer

[hadoop@master hbase]$ jps
7312 Jps
12178 ResourceManager
11540 NameNode
11943 SecondaryNameNode
12312 NodeManager
11707 DataNode
3933 HMaster
7151 HRegionServer

4、使用 Hbase Shell

[hadoop@master hbase]$ hbase shell
2016-11-07 10:35:05,262 WARN  [main] util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
SLF4J: Class path contains multiple SLF4J bindings.

SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [org.slf4j.impl.Log4jLoggerFactory]
HBase Shell; enter 'help<RETURN>' for list of supported commands.
Type "exit<RETURN>" to leave the HBase Shell
Version 1.2.3, rbd63744624a26dc3350137b564fe746df7a721a4, Mon Aug 29 15:13:42 PDT 2016

1) 查看集群状态和版本信息

hbase(main):001:0> status
1 active master, 0 backup masters, 1 servers, 0 dead, 1.0000 average load

hbase(main):002:0> version
1.2.3, rbd63744624a26dc3350137b564fe746df7a721a4, Mon Aug 29 15:13:42 PDT 2016

2) 创建 user 表和三个列族

hbase(main):003:0> create 'user','user_id','address','info'
0 row(s) in 2.3570 seconds

=> Hbase::Table - user

3) 查看所有表

hbase(main):005:0> create 'tmp', 't1', 't2'
0 row(s) in 1.2320 seconds

=> Hbase::Table - tmp
hbase(main):
006:0> list TABLE tmp user 2 row(s) in 0.0100 seconds => ["tmp", "user"] hbase(main):007:0>

4) 查看表结构

hbase(main):008:0> describe 'user'
Table user is ENABLED                                                                                                                                                                        
user                                                                                                                                                                                         
COLUMN FAMILIES DESCRIPTION                                                                                                                                                                  
{NAME => 'address', BLOOMFILTER => 'ROW', VERSIONS => '1', IN_MEMORY => 'false', KEEP_DELETED_CELLS => 'FALSE', DATA_BLOCK_ENCODING => 'NONE', TTL => 'FOREVER', COMPRESSION => 'NONE', MIN_V
ERSIONS => '0', BLOCKCACHE => 'true', BLOCKSIZE => '65536', REPLICATION_SCOPE => '0'}                                                                                                        
{NAME => 'info', BLOOMFILTER => 'ROW', VERSIONS => '1', IN_MEMORY => 'false', KEEP_DELETED_CELLS => 'FALSE', DATA_BLOCK_ENCODING => 'NONE', TTL => 'FOREVER', COMPRESSION => 'NONE', MIN_VERS
IONS => '0', BLOCKCACHE => 'true', BLOCKSIZE => '65536', REPLICATION_SCOPE => '0'}                                                                                                           
{NAME => 'user_id', BLOOMFILTER => 'ROW', VERSIONS => '1', IN_MEMORY => 'false', KEEP_DELETED_CELLS => 'FALSE', DATA_BLOCK_ENCODING => 'NONE', TTL => 'FOREVER', COMPRESSION => 'NONE', MIN_V
ERSIONS => '0', BLOCKCACHE => 'true', BLOCKSIZE => '65536', REPLICATION_SCOPE => '0'}                                                                                                        
3 row(s) in 0.2060 seconds

hbase(main):009:0>

5) 删除表

hbase(main):010:0> disable 'tmp'
0 row(s) in 2.2580 seconds

hbase(main):011:0> drop 'tmp'
0 row(s) in 1.2560 seconds

hbase(main):012:0>

5、停止 Hbase

[hadoop@master hbase]$ stop-hbase.sh 
stopping hbase......................
localhost: no zookeeper to stop because no pid file /tmp/hbase-hadoop-zookeeper.pid

停止 Hadoop 的顺序是停止 hbase、停止 YARN、停止 Hdfs

6、web 使用

可通过 Hdfs 页面 http://10.1.2.108:50070 进入 Hbase 页面

或者直接访问 http://10.1.2.108:60010/master.jsp
