• Hadoop2.x下安装HBase


    1.安装好 hadoop 集群,并启动 

    [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 官方文档(http://hbase.apache.org/book.html#basic.prerequisites),找到与 hadoop 版本对应的 hbase 并下载 

    [grid@hadoop4 ~]$ wget http://mirrors.cnnic.cn/apache/hbase/hbase-1.0.0/hbase-1.0.0-bin.tar.gz 

    3.解压 

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

    4.进入 hbase 的 lib 目录,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 

    发现与 hadoop 集群的版本号不一致,需要用 hadoop 目录下的 jar 替换 hbase/lib 目录下的 jar 文件。 
    编写脚本来完成替换,如下所示: 
    [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 包替换成功;hbase/lib 目录下还有个 slf4j-log4j12-XXX.jar,在机器有装hadoop时,由于classpath中会有hadoop中的这个jar包,会有冲突,直接删除掉

    [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 

    第一个参数指定了JDK路径;第二个参数指定了 hadoop 的配置文件路径;第三个参数设置使用 hbase 默认自带的 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>

    创建目录

    [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.设置环境变量 

    [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.分发 hbase 到其它机器,并在其上设置环境变量 

    [grid@hadoop4 ~]$ scp -r hbase-1.0.0 grid@hadoop5:~ 
    [grid@hadoop4 ~]$ scp -r hbase-1.0.0 grid@hadoop6:~ 

    8.启动 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查看发现 Master 机上 HRegionServer 服务未启动,查看日志显示因16020端口被占用导致 HRegionServer 启动失败,查证发现占用16020端口的是 HMaster 进程,查看官方文档后解决:
    [grid@hadoop4 ~]$ sh local-regionservers.sh start 2 

    官方文档截图: 
     

    9.shell 

     

    10.Web管理界面
