HBase完全分布模式安装

假设Hadoop已经成功安装。

实验环境如下：

centos 6.4

hadoop-0.20.2

hbase-0.90.5

 

 

 

用户名root

hadoop安装目录：/root/bin/hadoop-0.20.2

hbase计划安装目录：/root/bin/hbase-0.90.5

 

大致过程为：首先在masternode上安装hbase，配置好后再拷贝至slave机器。

（1）下载hbase-0.90.5.tar.gz，解压到/root/bin/hbase-0.90.5

（2）编辑/root/bin/hbase-0.90.5/conf/hbase-env.sh，编辑后如下所示，带颜色的部分为修改部分：

#

#

 

# Set environment variables here.

 

# The java implementation to use.  Java 1.6 required. Java安装目录，最低1.6版本

export JAVA_HOME=/root/bin/jdk1.6.0_26

 

# Extra Java CLASSPATH elements.  Optional. 整合hadoop的配置文件

export HBASE_CLASSPATH=/root/bin/hadoop-0.20.2/conf

 

# The maximum amount of heap to use, in MB. Default is 1000.

# export HBASE_HEAPSIZE=1000

 

# Extra Java runtime options.

# Below are what we set by default.  May only work with SUN JVM.

# For more on why as well as other possible settings,

# see http://wiki.apache.org/hadoop/PerformanceTuning

export HBASE_OPTS="-ea -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode"

 

# Uncomment below to enable java garbage collection logging in the .out file.

# export HBASE_OPTS="$HBASE_OPTS -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCDateStamps" 

 

# Uncomment and adjust to enable JMX exporting

# See jmxremote.password and jmxremote.access in $JRE_HOME/lib/management to configure remote password access.

# More details at: http://java.sun.com/javase/6/docs/technotes/guides/management/agent.html

#

# export HBASE_JMX_BASE="-Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false"

# export HBASE_MASTER_OPTS="$HBASE_JMX_BASE -Dcom.sun.management.jmxremote.port=10101"

# export HBASE_REGIONSERVER_OPTS="$HBASE_JMX_BASE -Dcom.sun.management.jmxremote.port=10102"

# export HBASE_THRIFT_OPTS="$HBASE_JMX_BASE -Dcom.sun.management.jmxremote.port=10103"

# export HBASE_ZOOKEEPER_OPTS="$HBASE_JMX_BASE -Dcom.sun.management.jmxremote.port=10104"

 

# File naming hosts on which HRegionServers will run.  $HBASE_HOME/conf/regionservers by default.

# export HBASE_REGIONSERVERS=${HBASE_HOME}/conf/regionservers

 

# Extra ssh options.  Empty by default.

# export HBASE_SSH_OPTS="-o ConnectTimeout=1 -o SendEnv=HBASE_CONF_DIR"

 

# Where log files are stored.  $HBASE_HOME/logs by default.  hbase日志目录，注意logs目录需创建

export HBASE_LOG_DIR=/root/bin/hbase-0.90.5/logs

 

# A string representing this instance of hbase. $USER by default.

# export HBASE_IDENT_STRING=$USER

 

# The scheduling priority for daemon processes.  See 'man nice'.

# export HBASE_NICENESS=10

 

# The directory where pid files are stored. /tmp by default.

# export HBASE_PID_DIR=/var/hadoop/pids

 

# Seconds to sleep between slave commands.  Unset by default.  This

# can be useful in large clusters, where, e.g., slave rsyncs can

# otherwise arrive faster than the master can service them.

# export HBASE_SLAVE_SLEEP=0.1

 

# Tell HBase whether it should manage it's own instance of Zookeeper or not.开启zookeeper

export HBASE_MANAGES_ZK=true

 

 

（3）编辑/home/grid/hbase/conf/hbase-site.xml，默认内无属性，均需自行添加：

<configuration>
        <property>
               <name>hbase.rootdir</name>
               <value>hdfs://master:9000/hbase</value>
        </property>
        <property>
                <name>hbase.cluster.distributed</name>
                <value>true</value>
        </property>
        <property>
                <name>hbase.master</name>
                <value>master:60000</value>
        </property>
        <property>
                 <name>hbase.zookeeper.quorum</name>
                 <value>master,slave1,slave2</value>
         </property>
</configuration>

（4）编辑/root/bin/conf/regionservers，将所有的slavenode添加到这个文件，类似与hadoop中slaves文件，该文件原本为空，如下是我添加的内容，两台slavenode机器的域名（hosts文件中已做解析）：

slave1

slave2

（5）解决版本、jar包冲突：

 

 

（5）将master节点上已经配置好的hbase文件夹拷贝到slave节点，执行：

 

（6）启动

1）启动hadoop：/root/bin/hadoop-0.20.2/bin/start-all.sh

执行命令后用jps命令验证，显示：

 

3549 Jps

2438 NameNode

2758 JobTracker

2690 SecondaryNameNode

 

说明hadoop启动成功。

2）启动hbase：/root/bin/hbase/bin/start-hbase.sh

执行命令后用jps命令验证，显示：

 

3750 Jps

3652 HMaster

2438 NameNode

2758 JobTracker

2690 SecondaryNameNode

 

说明hbase启动成功，然后分别到两台slave机器上执行jps，slave1上执行jps，显示：

 

2676 TaskTracker

2504 DataNode

3800 Jps

3501 HQuorumPeer

3669 HRegionServer

 

注意：其中HQuorumPeer是zookeeper进程，在hbase-site.xml中的hbase.zookeeper.quorum属性中为slavenode1配置了zookeeper；

slavenode2上执行jps，显示：

 

2663 TaskTracker

2482 DataNode

3607 Jps

3530 HRegionServer

 

（8）进入hbase

在master机器执行hbase/bin/hbase shell即可进入hbase的shell

 

grid@masternode:~$ hbase/bin/hbase shell

HBase Shell; enter 'help' for list of supported commands.

Type "exit" to leave the HBase Shell

Version 0.90.5, r1212209, Fri Dec  9 05:40:36 UTC 2011
