如何分布式安裝Hbase

這篇文章將為大家詳細講解有關如何分布式安裝Hbase，小編覺得挺實用的，因此分享給大家做個參考，希望大家閱讀完這篇文章后可以有所收獲。

[hadoop@master conf]$ pwd

/home/hadoop/hbase/conf

[hadoop@master conf]$ vim hbase-env.sh

[hadoop@master conf]$

export HBASE_CLASSPATH=/home/hadoop/hadoop/conf

BASE_MANAGES_ZK=true

[hadoop@master conf]$ vim hbase-site.xml

如果想知道默認參數在哪里可以

[hadoop@master hbase]$ find . -name "*default*"

./docs/hbase-default.xml

./src/main/resources/hbase-default.xml

[hadoop@master hbase]$ vim src/main/resources/hbase-default.xml

查看

<configuration>

<property>

<name>hbase.rootdir</name>

<value>hdfs://master:9000/hbase</value>

</property>

<property>

<name>hbase.cluster.distributed</name>

<value>true</value>

</property>

</configuration>

拷貝驅動，因為要支持hadoop

[hadoop@master lib]$ ll hadoop-core-1.0.4.jar

-rw-r--r-- 1 hadoop hadoop 3929148 2014-01-11 hadoop-core-1.0.4.jar

這時候發現是hadoop 1.0.4  我們使用的是1.2.1

這個jar可以刪除，拷貝新的過來

[hadoop@master lib]$ mv hadoop-core-1.0.4.jar hadoop-core-1.0.4.sav

[hadoop@master lib]$ cp /home/hadoop/hadoop/hadoop-core-1.2.1.jar .

[hadoop@master lib]$ ll hadoop-core-1.

hadoop-core-1.0.4.sav  hadoop-core-1.2.1.jar 

到這里偽分布式ok

[hadoop@master conf]$ start-hbase.sh

The authenticity of host 'localhost (127.0.0.1)' can't be established.

RSA key fingerprint is 6d:ef:a5:75:27:1d:7f:60:eb:ef:bc:dc:7c:4d:f7:a4.

Are you sure you want to continue connecting (yes/no)? yes

localhost: Warning: Permanently added 'localhost' (RSA) to the list of known hosts.

[hadoop@master ~]$ hadoop fs -ls /

停止hbase

刪除這些內容

[hadoop@master ~]$ hadoop fs -ls /hbase

-rw-r--r--   2 hadoop supergroup          3 2014-10-24 02:33 /hbase/hbase.version

因為集群有唯一的東西比如ID

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

stopping hbase...........

localhost: stopping zookeeper.

[hadoop@master ~]$

[hadoop@master ~]$ hadoop fs -rmr /hbase

Deleted hdfs://master:9000/hbase

[hadoop@master ~]$
