首先声明，我是一个菜鸟。一下文章中现出技术误导情况盖不负责

基于Hadoop集群的HBase集群的配置

1.准备工作

a.经已实现安装的Hadoop集群环境

b.所须要的软件包

zookeeper-3.4.4.tar.gz下载地址：

http://downloads.gotsoft.com/pub/apache/zookeeper/zookeeper-3.4.4/

hbase-0.94.6.1tar.gz下载地址：

http://labs.mop.com/apache-mirror/hbase/stable/hbase-0.94.6.1.tar.gz

2.独单安装的ZooKeeper集群，不基于Hbase集群管理

a.在Master节点上解压zookeeper

l  ##提议用使hduser权限，免避后之现出SSH错误

hduser@master:/usr/local$sudo tar -zxvfzookeeper-3.4.4.tar.gz

l  ##server前面的数字是zooKeeper识别时后的Id，须要与前面的置设保持一致

hduser@master:/usr/local$tvi /zookeeper/conf/zoo.cfg

tickTime=2000

initLimit=5

syncLimit=2

dataDir=/data/zookeeper

clientPort=2181

server.1=master:2888:3888

server.2=slave1:2888:3888

server.3=slave2:2888:3888

root@master:/usr/local# chown -Rhduser:hadoop zookeeper

3.将zookeeper复制到其他呆板

hduser@master:/usr/local$scp -r zookeeper-3.4.5hduser@slave1:/home/hduser

hduser@master:/usr/local$ scp -rzookeeper-3.4.5 hduser@slave2:/home/hduser

hduser@slave1:~#sudomv zookeeper-3.4.5/ /usr/local/zookeeper-3.4.5

hduser@slave2:~$sudomv zookeeper-3.4.5/ /usr/local/zookeeper-3.4.5

4.在每台呆板配置的dataDir目录上面，创立myid文件标记前当机主

Master：     $touch /data/zookeeper/myid

$echo "1" >/data/zookeeper/myid

Slave1：      $mkdir -p /data/zookeeper

$touch /data/zookeeper/myid

$echo "3" > /data/zookeeper/myid

Slave2:       $mkdir -p/data/zookeeper

$touch /data/zookeeper/myid

$echo "5" > /data/zookeeper/myid

5. 动启zookeeper集群

hduser@master:/usr/local/zookeeper/bin$./zkServer.sh start
JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
【题问1】Starting zookeeper ... ./zkServer.sh: line 113:/data/zookeeper/zookeeper_server.pid: Permission denied
FAILED TO WRITE PID

因原是刚才/data/zookeeper是root权限，而不是hduser的，改修权限之~

【题问1处理】root@master:/# chown -Rhduser:hadoop /data

其他两个slave节点也一样~

然后题问处理：

hduser@master:/usr/local/zookeeper$ cd bin
hduser@master:/usr/local/zookeeper/bin$ ./zkServer.sh start
JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

其他节点也样同动启zookeeper~
hduser@master:/usr/local/zookeeper/bin$

hduser@slave1:/usr/local/zookeeper/bin$./zkServer.sh status
JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
【题问2】Error contacting service. It is probably notrunning.

1）查看zoopkeeper.out

r@232] - Unexpected exception,tries=0, connecting to slave1/192.168.123.12:2888

【错误2处理】没有将zookeeper复制到其他的节点！！！

没有在个每节点动启zookeeper

6.安装配置Hbase集群

a>动启HDFS集群例实,并创立目录

##hdfs://master01:54310/hbase【注意与hadoop，core-site.xml中的fs.default.name中的端口号保持一致，一统置设为54310；hbase-site.xml中的hbase:rootdir中的端口号】

hduser@master:/usr/local/hadoop$bin/hadoop fs -mkdir /hbase

Warning: $HADOOP_HOME is deprecated.

hduser@master:/usr/local/hadoop$

Call tomaster/127.0.1.1:54310 failed【改修localhost地址为127.0.0.1】

HBASE SHELL 错误NativeException: org.apache.hadoop.hbase.MasterNotRunningException:null

【处理步调：】

1、动启hadoop后，须要等一段时间，再开启hbase

2、去失落hadoop的安全模式：

hadoop dfsadmin -safemode leave

3、把/etc/hosts里的master01的IP为改服务器前当的IP

4、确认hbase的hbase-site.xml中

<name>hbase.rootdir</name>

<value>hdfs://localhost:8020/hbase</value>

与hadoop的core-site.xml中

<name>fs.default.name</name>

<value>hdfs://localhost:8020</value>

红字分部保持一致

5、确认hadoop版本是0.20.2，hbase版本是0.20.6

6、从新执行./start-hbase.sh之前，先kill失落前当的hbase和zookeeper程进

后之再执行：

$bin/hadoop fs -mkdir /hbase

b> 解压hbase-0.94.5.tar.gz，改修配置文件，正式安装HBase：

l  #vi hbase-0.94.5/conf/hbase-env.sh

exportJAVA_HOME=/usr/java/jdk1.6.0_43

exportHBASE_CLASSPATH=$HBASE_HOME/

#exportHBASE_HEAPSIZE=128

#exportHBASE_OPTS="-XX:+UseConcMarkSweepGC"

exportHBASE_MANAGES_ZK=false

#vi hbase-0.94.5/conf/regionservers

slave1

slave2

l  将hbase-webapps目录改名为webapps

hduser@master:/usr/local/hbase-0.94.6$ mvhbase-webapps/ /webapps

l  检查HBase配置，复制到其他的slave节点：

hduser@master:/usr/local$ scp -rhbase-0.94.6 hduser@slave1:/home/hduser/

hduser@master:/usr/local$ scp -rhbase-0.94.6 hduser@slave2:/home/hduser/

l  动启HBase：

hduser@master:/usr/local$ ./hbase-0.94.6/bin/start-hbase.sh
starting master, logging to/usr/local/hbase-0.94.6/bin/../logs/hbase-hduser-master-master.out
slave2: starting regionserver, logging to/usr/local/hbase-0.94.6/bin/../logs/hbase-hduser-regionserver-slave2.out
slave1: starting regionserver, logging to/usr/local/hbase-0.94.6/bin/../logs/hbase-hduser-regionserver-slave1.out

l  查看关相程进：

hduser@master:/usr/local$ jps

3339 QuorumPeerMain

8210 JobTracker

7894 DataNode

9187 HMaster

8126 SecondaryNameNode

hduser@slave2:/usr/local/hbase-0.94.6$ jps

5083 TaskTracker

5544 Jps

4877 DataNode

3042 QuorumPeerMain

【错误】13/04/27 05:47:21ERROR client.HConnectionManager$HConnectionImplementation: Check the valueconfigured in 'zookeeper.znode.parent'. There could be a mismatch with the oneconfigured in the master.

l  去失落hadoop的安全模式

hduser@master:/usr/local/hadoop$ bin/hadoopdfsadmin -safemode leave
Warning: $HADOOP_HOME is deprecated.

Safe mode is OFF

文章结束给大家分享下程序员的一些笑话语录： 3G普不普及现在已经不是看终端了，而是看应用，有好的，便宜实用的应用，花1000多买个能用的智能手机应该不是什么难事。反过来说，你200元拿一个智能手机，没有好的应用，看个电影要几十元，也是没人用3G。
