1.基本信息
| 版本 | 1.2.4 |
|---|---|
| 安装机器 | 三台机器 |
| 账号 | hadoop |
| 源路径 | /opt/software/hbase-1.2.4-bin.tar.gz |
| 目标路径 | /opt/hbase -> /opt/hbase-1.2.4 |
| 依赖关系 | 无 |
2.安装过程
1).使用hadoop账号解压到/opt/hadoop目录下并设置软连接：
[root
@bgs
-5p173-wangwenting opt]# su hadoop
[hadoop
@bgs
-5p173-wangwenting opt]$ cd /opt/software
[hadoop
@bgs
-5p173-wangwenting software]$ tar -zxvf hbase-${version}-bin.tar.gz -C /opt
[hadoop
@bgs
-5p173-wangwenting software]$ cd /opt
[hadoop
@bgs
-5p173-wangwenting opt]$ ln -s hbase-${version}/ hbase
|
2).进入/opt/hbase/conf目录,修改hbase-env.sh文件内容:
[hadoop
@bgs
-5p173-wangwenting opt]$ cd /opt/hbase/conf
[hadoop
@bgs
-5p173-wangwenting opt]$ vim hbase-env.sh
export JAVA_HOME=/opt/java
export HBASE_PID_DIR=/opt/pids
export HADOOP_HOME=/opt/hadoop
export HBASE_HOME=/opt/hbase
|
3).修改hbase-site.xml文件内容:
[hadoop
@bgs
-5p173-wangwenting opt]$ vim hbase-site.xml
添加下面内容
<configuration>
<property>
<name>hbase.rootdir</name>
<value>hdfs:
//bgs-5p173-wangwenting:9000/hbase</value>
</property>
<property>
<name>hbase.cluster.distributed</name>
<value>
true
</value>
</property>
<property>
<name>hbase.zookeeper.quorum</name>
<value>bgs-5p173-wangwenting,bgs-5p174-wangwenting,bgs-5p175-wangwenting</value>
</property>
</configuration>
|
4).修改/opt/hadoop/hbase/conf/regionservers文件内容:
[hadoop
@bgs
-5p173-wangwenting opt]$ vim /opt/hbase/conf/regionservers
添加以下内容：
bgs-5p174-wangwenting
bgs-5p175-wangwenting
|
5).通过scp复制到其它两台机器上:
[hadoop
@bgs
-5p173-wangwenting opt]$ scp -r /opt/hbase-${version} hadoop
@bgs
-5p174-wangwenting:/opt
[hadoop
@bgs
-5p174-wangwenting opt]$ ln -s hbase-${version}/ hbase
[hadoop
@bgs
-5p173-wangwenting opt]$ scp -r /opt/hbase-${version} hadoop
@bgs
-5p175-wangwenting:/opt
[hadoop
@bgs
-5p175-wangwenting opt]$ ln -s hbase-${version}/ hbase
|
6).在bgs-5p173-wangwenting上启动hbase集群:
[hadoop
@bgs
-5p173-wangwenting opt]$ /opt/hbase/bin/start-hbase.sh
|
7).查看集群是否启动，运行jps
[hadoop
@bgs
-5p173-wangwenting opt]$ jps
若bgs-5p173-wangwenting如下所示：
22898
ResourceManager
20739
Jps
24383
JobHistoryServer
20286
HMaster
22722
SecondaryNameNode
22488
NameNode
[hadoop
@bgs
-5p174-wangwenting opt]$ jps
2141
NodeManager
3257
HRegionServer
25283
Jps
1841
DataNode
[hadoop
@bgs
-5p175-wangwenting opt]$ jps
2141
NodeManager
3257
HRegionServer
25283
Jps
1841
DataNode
显示有HMaster和HRegionServer,则说明启动成功
|
8).使用/opt/hadoop/hbase/bin/hbase shell命令测试安装结果:
[hadoop
@bgs
-5p173-wangwenting opt]$ /opt/hbase/bin/hbase shell
|
a.创建表test:
hbase(main):
002
:
0
> create
"test"
,
"cf"
0
row(s) in
2.5840
seconds
=> Hbase::Table - test
|
b.列出全部表:
hbase(main):
003
:
0
> list
TABLE
test
1
row(s) in
0.0310
seconds
=> [
"test"
]
|
如果在输入list,有好几次，启动Hadoop和HBase之后，执行jps命令，已经看到有HMaster的进程，但是进入到HBase的shell，执行一个命令，会出现下面的错误：
解决方法：
进入到logs目录查看master的日志：发现一直显示下面的内容：
vim hbase-hadoop-master-s1.log
2017-03-13 17:13:17,374 INFO org.apache.hadoop.hbase.util.FSUtils: Waiting for dfs to exit safe mode... 2017-03-13 17:13:27,377 INFO org.apache.hadoop.hbase.util.FSUtils: Waiting for dfs to exit safe mode... 2017-03-13 17:13:37,386 INFO org.apache.hadoop.hbase.util.FSUtils: Waiting for dfs to exit safe mode... 2017-03-13 17:13:47,393 INFO org.apache.hadoop.hbase.util.FSUtils: Waiting for dfs to exit safe mode... 2017-03-13 17:13:57,395 INFO org.apache.hadoop.hbase.util.FSUtils: Waiting for dfs to exit safe mode... 2017-03-13 17:14:07,409 INFO org.apache.hadoop.hbase.util.FSUtils: Waiting for dfs to exit safe mode...
原来是Hadoop在刚启动的时候，还处在安全模式造成的,手动退出Hadoop的安全模式.然后重新启动hbase服务。
重启后输入list，便不再报错了。
c.插入数据到test表:
hbase(main):
001
:
0
> put
"test"
,
"row"
,
"cf:a"
,
"value"
0
row(s) in
0.4150
seconds
|
d.查看test表信息:
hbase(main):
002
:
0
> scan
'test'
ROW COLUMN+CELL
row column=cf:a, timestamp=
1447246157917
, value=value
1
row(s) in
0.0270
seconds
|
若hbase shell测试成功，则进入浏览器访问以下网址:http://172.24.5.173:16010/，
若正常显示，则hbase集群安装成功! 用ip保险一点，用域名首先要在自己的电脑host文件中配置。
9).启动thriftserver2服务
[hadoop
@bgs
-5p173-wangwenting opt]$ nohup /opt/hbase/bin/hbase-daemon.sh start thrift2 &
