Hadoop2.x下安裝HBase

環境：CentOS6.5  Hadoop2.5.2  HBase1.0.0

1.安裝好 hadoop 集羣，並啓動
[grid@hadoop4 ~]$ sh hadoop-2.5.2/sbin/start-dfs.sh
[grid@hadoop4 ~]$ sh hadoop-2.5.2/sbin/start-yarn.sh
查看 hadoop 版本：
[grid@hadoop4 ~]$ hadoop-2.5.2/bin/hadoop version
Hadoop 2.5.2
Subversion Unknown -r Unknown
Compiled by grid on 2014-12-31T01:40Z
Compiled with protoc 2.5.0
From source with checksum df7537a4faa4658983d397abf4514320
This command was run using /home/grid/hadoop-2.5.2/share/hadoop/common/hadoop-common-2.5.2.jar

2.查看 hbase 官方文檔（http://hbase.apache.org/book.html#basic.prerequisites），找到與 hadoop 版本對應的 hbase 並下載
[grid@hadoop4 ~]$ wget http://mirrors.cnnic.cn/apache/hbase/hbase-1.0.0/hbase-1.0.0-bin.tar.gz

3.解壓
[grid@hadoop4 ~]$ tar -zxf hbase-1.0.0-bin.tar.gz

4.進入 hbase 的 lib 目錄，查看 hadoop jar 包的版本
[grid@hadoop4 ~]$ cd hbase-1.0.0/lib/
[grid@hadoop4 lib]$ find -name 'hadoop*jar'
./hadoop-common-2.5.1.jar
./hadoop-mapreduce-client-common-2.5.1.jar
./hadoop-annotations-2.5.1.jar
./hadoop-yarn-server-common-2.5.1.jar
./hadoop-hdfs-2.5.1.jar
./hadoop-client-2.5.1.jar
./hadoop-mapreduce-client-shuffle-2.5.1.jar
./hadoop-yarn-common-2.5.1.jar
./hadoop-yarn-server-nodemanager-2.5.1.jar
./hadoop-yarn-client-2.5.1.jar
./hadoop-mapreduce-client-core-2.5.1.jar
./hadoop-auth-2.5.1.jar
./hadoop-mapreduce-client-app-2.5.1.jar
./hadoop-yarn-api-2.5.1.jar
./hadoop-mapreduce-client-jobclient-2.5.1.jar
發現與 hadoop 集羣的版本號不一致，須要用 hadoop 目錄下的 jar 替換 hbase/lib 目錄下的 jar 文件。
編寫腳原本完成替換，以下所示：

[grid@hadoop4 lib]$ pwd
/home/grid/hbase-1.0.0/lib
[grid@hadoop4 lib]$ vim f.sh
find -name "hadoop*jar" | sed 's/2.5.1/2.5.2/g' | sed 's/\.\///g' > f.log
rm ./hadoop*jar
cat ./f.log | while read Line
do
find /home/grid/hadoop-2.5.2 -name "$Line" | xargs -i cp {} ./
done
rm ./f.log
[grid@hadoop4 lib]$ chmod u+x f.sh
[grid@hadoop4 lib]$ ./f.sh
[grid@hadoop4 lib]$ find -name 'hadoop*jar'
./hadoop-yarn-api-2.5.2.jar
./hadoop-mapreduce-client-app-2.5.2.jar
./hadoop-common-2.5.2.jar
./hadoop-mapreduce-client-jobclient-2.5.2.jar
./hadoop-mapreduce-client-core-2.5.2.jar
./hadoop-yarn-server-nodemanager-2.5.2.jar
./hadoop-hdfs-2.5.2.jar
./hadoop-yarn-common-2.5.2.jar
./hadoop-mapreduce-client-shuffle-2.5.2.jar
./hadoop-auth-2.5.2.jar
./hadoop-mapreduce-client-common-2.5.2.jar
./hadoop-yarn-client-2.5.2.jar
./hadoop-annotations-2.5.2.jar
./hadoop-yarn-server-common-2.5.2.jar

OK，jar 包替換成功；hbase/lib 目錄下還有個 slf4j-log4j12-XXX.jar，在機器有裝hadoop時，因爲classpath中會有hadoop中的這個jar包，會有衝突，直接刪除掉

[grid@hadoop4 lib]$ rm `find -name 'slf4j-log4j12-*jar'`

5.修改配置文件

5.1.
[grid@hadoop4 hbase-1.0.0]$ vi conf/hbase-env.sh
export JAVA_HOME=/usr/java/jdk1.7.0_72
export HBASE_CLASSPATH=/home/grid/hadoop-2.5.2/etc/hadoop
export HBASE_MANAGES_ZK=true
第一個參數指定了JDK路徑；第二個參數指定了 hadoop 的配置文件路徑；第三個參數設置使用 hbase 默認自帶的 Zookeeper

5.2.
[grid@hadoop4 hbase-1.0.0]$ vim conf/hbase-site.xml

<property>
<name>hbase.rootdir</name>
<value>hdfs://hadoop4:9000/hbase</value>
</property>
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>
<property>
<name>hbase.tmp.dir</name>
<value>/home/grid/hbase-1.0.0/tmp</value>
</property>
<property>
<name>hbase.zookeeper.quorum</name>
<value>hadoop4,hadoop5,hadoop6</value>
</property>
<property>
<name>hbase.zookeeper.property.dataDir</name>
<value>/home/grid/hbase-1.0.0/zookeeper</value>
</property>

建立目錄

[grid@hadoop4 hbase-1.0.0]$ mkdir tmp
[grid@hadoop4 hbase-1.0.0]$ mkdir zookeeper

5.3.
[grid@hadoop4 hbase-1.0.0]$ vim conf/regionservers
hadoop4
hadoop5
hadoop6

6.設置環境變量
[grid@hadoop4 ~]$ vi .bash_profile
export HBASE_HOME=/home/grid/hbase-1.0.0
export PATH=$PATH:$HBASE_HOME/bin
[grid@hadoop4 ~]$ source .bash_profile

7.分發 hbase 到其它機器，並在其上設置環境變量
[grid@hadoop4 ~]$ scp -r hbase-1.0.0 grid@hadoop5:~
[grid@hadoop4 ~]$ scp -r hbase-1.0.0 grid@hadoop6:~

8.啓動 hbase
[grid@hadoop4 ~]$ sh start-hbase.sh
[grid@hadoop4 ~]$ jps
2388 ResourceManager
3692 Jps
2055 NameNode
3375 HQuorumPeer
2210 SecondaryNameNode
3431 HMaster
[grid@hadoop5 ~]$ jps
2795 Jps
2580 HQuorumPeer
2656 HRegionServer
2100 NodeManager
1983 DataNode
[grid@hadoop6 ~]$ jps
2566 HQuorumPeer
1984 DataNode
2101 NodeManager
2803 Jps
2639 HRegionServer
jps查看發現 Master 機上 HRegionServer 服務未啓動，查看日誌顯示因16020端口被佔用致使 HRegionServer 啓動失敗，查證發現佔用16020端口的是 HMaster 進程，查看官方文檔後解決：[grid@hadoop4 ~]$ sh local-regionservers.sh start 2
