问题导读:
1.hadoop ha是通过什么配置实现自动切换的?
2.配置中mapred与mapreduce的区别是什么?
3.hadoop ha两个namenode之间的关系是什么?

-- 注意:1、以mapred.开头的形式去指定属性名,都是一种过时的形式,建议使用mapreduce.
比如:mapred.compress.map.output 属性应该对应修改成:mapreduce.map.output.compress

当然,好像还有少量属性名是没有修改的,比如:mapred.child.java.opts、mapred.child.env

-- Step 5. 启动Zookeeper、JournalNode、格式化Hadoop集群并启动
-- Step 5.1 启动Zooker (ZK集群是funshion-hadoop194、funshion-hadoop195、funshion-hadoop196、funshion-hadoop197、funshion-hadoop198 五台服务器)
[hadoop@funshion-hadoop194 bin]$ /usr/local/zookeeper/bin/zkServer.sh start
[hadoop@funshion-hadoop195 bin]$ /usr/local/zookeeper/bin/zkServer.sh start
[hadoop@funshion-hadoop196 bin]$ /usr/local/zookeeper/bin/zkServer.sh start
[hadoop@funshion-hadoop197 bin]$ /usr/local/zookeeper/bin/zkServer.sh start
[hadoop@funshion-hadoop198 bin]$ /usr/local/zookeeper/bin/zkServer.sh start
-- 可以如下查看Zookeeper集群各节点的状态:
/usr/local/zookeeper/bin/zkServer.sh status
-- 然后在某一个namenode节点执行如下命令,创建命名空间
[hadoop@funshion-hadoop194 bin]$ cd $HADOOP_HOME
[hadoop@funshion-hadoop194 hadoop]$ ./bin/hdfs zkfc -formatZK
-- 备注:停止zookeeper相关命令类似如下:
/usr/local/zookeeper/bin/zkServer.sh stop
/usr/local/zookeeper/bin/zkServer.sh restart
-- Step 5.2 启动JournalNode进程(在funshion-hadoop194、funshion-hadoop195、funshion-hadoop196、funshion-hadoop197、funshion-hadoop198五台服务器上分别执行):
[hadoop@funshion-hadoop194 bin]$ $HADOOP_HOME/sbin/hadoop-daemon.sh start journalnode
[hadoop@funshion-hadoop195 bin]$ $HADOOP_HOME/sbin/hadoop-daemon.sh start journalnode
[hadoop@funshion-hadoop196 bin]$ $HADOOP_HOME/sbin/hadoop-daemon.sh start journalnode
[hadoop@funshion-hadoop197 bin]$ $HADOOP_HOME/sbin/hadoop-daemon.sh start journalnode
[hadoop@funshion-hadoop198 bin]$ $HADOOP_HOME/sbin/hadoop-daemon.sh start journalnode
-- Step 5.3 格式化Hadoop集群并启动:
-- 在 funshion-hadoop194 上执行:
[hadoop@funshion-hadoop194 bin]$ $HADOOP_HOME/bin/hdfs namenode -format mycluster
[hadoop@funshion-hadoop194 bin]$ $HADOOP_HOME/sbin/hadoop-daemon.sh start namenode
-- 上步执行完后,在 funshion-hadoop195 上执行:
[hadoop@funshion-hadoop195 bin]$ $HADOOP_HOME/bin/hdfs namenode -bootstrapStandby
[hadoop@funshion-hadoop195 bin]$ $HADOOP_HOME/sbin/hadoop-daemon.sh start namenode
-- 上步执行完后,可以继续在某个 namenode 执行 $HADOOP_HOME/sbin/start-all.sh 启动datanode及yarn相关进程。
-- 因为是配置的自动故障转移,所以不能手工切换namenode的active和stadby角色。
-- 可以通过haadmin查看每个Service的角色状态:
[hadoop@funshion-hadoop194 lab]$ $HADOOP_HOME/bin/hdfs haadmin -getServiceState nn1
standby
[hadoop@funshion-hadoop194 lab]$ $HADOOP_HOME/bin/hdfs haadmin -getServiceState nn2
active
[hadoop@funshion-hadoop194 lab]$
-- 通过hdfs-site.xml中的如下配置,我们知道nn1是在 funshion-hadoop194上的namenode服务,nn2是funshion-hadoop195上的namenode服务
<property>
<name>dfs.namenode.rpc-address.mycluster.nn1</name>
<value>funshion-hadoop194:8020</value>
</property>
<property>
<name>dfs.namenode.rpc-address.mycluster.nn2</name>
<value>funshion-hadoop195:8020</value>
</property>
-- 所以,我们可以尝试 kill 掉 nn2(状态为active的namenode进程,然后去查看nn1的角色是否改变:
[hadoop@funshion-hadoop195 bin]$ jps
3199 JournalNode
3001 NameNode
1161 QuorumPeerMain
3364 DFSZKFailoverController
4367 Jps
[hadoop@funshion-hadoop195 bin]$ kill -9 3001
[hadoop@funshion-hadoop195 bin]$ jps
3199 JournalNode
1161 QuorumPeerMain
3364 DFSZKFailoverController
4381 Jps
[hadoop@funshion-hadoop195 bin]$ $HADOOP_HOME/bin/hdfs haadmin -getServiceState nn1
active
[hadoop@funshion-hadoop195 bin]$ $HADOOP_HOME/sbin/hadoop-daemon.sh start namenode
starting namenode, logging to /usr/local/hadoop/logs/hadoop-hadoop-namenode-funshion-hadoop195.out
[hadoop@funshion-hadoop195 bin]$ $HADOOP_HOME/bin/hdfs haadmin -getServiceState nn1
active
[hadoop@funshion-hadoop195 bin]$ $HADOOP_HOME/bin/hdfs haadmin -getServiceState nn2
standby
-- 甚至可以直接reboot状态为active的namenode节点(执行操作系统的重启动作,看另一个standby状态的namenode节点是否能正常转换成acitve状态
-- 甚至可以在有作业运行的时候去执行reboot操作系统(namenode的active节点执行)以测试双节点故障转移是否确实健壮

-- ################################################################################## --
-- Step 7. Hive安装(安装到196机器) (使用Hive与HBase整合安装;使用源码编译安装)
-- (其实应该先安装hbase,再安装hive可能顺序合理一点)
-- 参考:https://cwiki.apache.org/conflue ... iorto0.13onHadoop23
http://www.hadoopor.com/thread-5470-1-1.html
http://blog.csdn.net/hguisu/article/details/7282050
http://blog.csdn.net/hguisu/article/details/7282050
http://www.micmiu.com/bigdata/hive/hive-hbase-integration/
-- 源码下载编译操作如下:
mkdir -p /opt/software/hive_src
cd /opt/software/hive_src/
svn checkout http://svn.apache.org/repos/asf/hive/trunk/ hive_trunk
cd /opt/software/hive_src/hive_trunk
-- 下载以后,我们检查 hive_trunk目录下的pom.xml文件,发现hadoop-23.version这个变量已经引用了hadoop 2.4.0版本,所以,我们可以什么也不用修改,直接用ant去编译:
<hadoop-23.version>2.4.0</hadoop-23.version>
-- 或者如果发现版本不正确的话,我们可以这样指定参数执行(也可以修改pom.xml文件中对应正确的hadoop、hbase、zookeeper版本):
-- 最后我选用的版本相关参数如下:
<hadoop-23.version>2.4.0</hadoop-23.version>
<hbase.hadoop1.version>0.98.3-hadoop1</hbase.hadoop1.version>
<hbase.hadoop2.version>0.98.3-hadoop2</hbase.hadoop2.version>
<zookeeper.version>3.4.6</zookeeper.version>
-- 最后,开始编译:

-- 最后,/opt/software/hive_src/hive_trunk/packaging/target 目录下的 apache-hive-0.14.0-SNAPSHOT-bin.tar.gz 文件,就是我们需要的安装包(这个版本还没有正式发布)
-- Step 7.1 My SQL安装(安装到194机器),并在My SQL中创建名为hive的数据库用以存放hive元数据:
-- 安装如下rpm包
rpm -ivh MySQL-client-5.6.17-1.linux_glibc2.5.x86_64.rpm
rpm -ivh MySQL-devel-5.6.17-1.linux_glibc2.5.x86_64.rpm
rpm -ivh MySQL-embedded-5.6.17-1.linux_glibc2.5.x86_64.rpm
rpm -e --nodeps mysql-libs-5.1.66-2.el6_3.x86_64
rpm -ivh MySQL-server-5.6.17-1.linux_glibc2.5.x86_64.rpm
rpm -ivh MySQL-shared-5.6.17-1.linux_glibc2.5.x86_64.rpm
rpm -ivh MySQL-shared-compat-5.6.17-1.linux_glibc2.5.x86_64.rpm
rpm -ivh MySQL-test-5.6.17-1.linux_glibc2.5.x86_64.rpm
A RANDOM PASSWORD HAS BEEN SET FOR THE MySQL root USER !
You will find that password in '/root/.mysql_secret'.
You must change that password on your first connect,
no other statement but 'SET PASSWORD' will be accepted.
See the manual for the semantics of the 'password expired' flag.
Also, the account for the anonymous user has been removed.
In addition, you can run:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test database.
This is strongly recommended for production servers.
See the manual for more instructions.
Please report any problems at http://bugs.mysql.com/
The latest information about MySQL is available on the web at

New default config file was created as /usr/my.cnf and
will be used by default by the server when you start it.
You may edit this file to change server settings

-- 另外,你必须在创建Hive库表前,在HDFS上创建/tmp和/user/hive/warehouse(也称为hive.metastore.warehouse.dir所指定的目录),并且将它们的权限设置为chmod g+w。完成这个操作的命令如下:
$ $HADOOP_HOME/bin/hadoop fs -mkdir /tmp
$ $HADOOP_HOME/bin/hadoop fs -mkdir /user/hive/warehouse
$ $HADOOP_HOME/bin/hadoop fs -chmod g+w /tmp
$ $HADOOP_HOME/bin/hadoop fs -chmod g+w /user/hive/warehouse

2.Hbase Compile
hbase-0.98.3/pom.xml 文件修改hadoop版本 2.2.0 -> 2.4.0
修改如下两个地方:
tar -xvf
-- 1.
<hadoop-two.version>2.4.0</hadoop-two.version>
-- 2.
<artifactId>hadoop-common</artifactId>
<version>2.4.0</version>
mvn clean package -DskipTests
但是没有看到有生成包,仔细找资料,获得打包过程。
hbase可以打包出hadoop1,也可以打包hadoop2,我们需要hadoop2,先生成pom.xml.hadoop2 文件,在打包:
bash ./dev-support/generate-hadoopX-poms.sh 0.98.1 0.98.1-hadoop2
MAVEN_OPTS="-Xmx3g" mvn -f pom.xml.hadoop2 clean install -DskipTests -Prelease
MAVEN_OPTS="-Xmx3g" mvn -f pom.xml.hadoop2 install -DskipTests site assembly:single -Prelease
10多分钟,编译目录有100多M大小,得到打包文件
hbase-0.98.1/hbase-assembly/target/hbase-0.98.1-hadoop2-bin.tar.gz

-- 最后,测试hive与hbase整合是否成功:
1、先在hive中创建hbase表:
[hadoop@funshion-hadoop196 ~]$ hive
Logging initialized using configuration in jar:file:/usr/local/apache-hive-0.14.0-SNAPSHOT-bin/lib/hive-common-0.14.0-SNAPSHOT.jar!/hive-log4j.properties
hive (default)> use web;
OK
Time taken: 0.813 seconds
hive (web)> CREATE TABLE hive_table_1(key int, value string)
> STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
> WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,id:1") TBLPROPERTIES ("hbase.table.name"="hive_table_1");
OK
Time taken: 4.471 seconds
hive (web)> desc hive_table_1;
OK
key int from deserializer
value string from deserializer
Time taken: 0.605 seconds, Fetched: 2 row(s)
2、然后在hbase查看表 hive_table_1 是否存在,并插入一行数据:
[hadoop@funshion-hadoop196 ~]$ hbase shell
2014-06-22 13:19:35,775 INFO [main] Configuration.deprecation: hadoop.native.lib is deprecated. Instead, use io.native.lib.available
2014-06-22 13:19:35,865 INFO [main] Configuration.deprecation: hadoop.native.lib is deprecated. Instead, use io.native.lib.available
2014-06-22 13:19:35,955 INFO [main] Configuration.deprecation: hadoop.native.lib is deprecated. Instead, use io.native.lib.available
2014-06-22 13:19:36,028 INFO [main] Configuration.deprecation: hadoop.native.lib is deprecated. Instead, use io.native.lib.available

=> ["hive_table_1", "testtable"]
hbase(main):005:0> put 'hive_table_1', "1", "id:1", "1"
0 row(s) in 0.8620 seconds
3、然后在hive中查询,看是否能访问到表数据:
hive (web)> select * from hive_table_1;
OK
1 1
Time taken: 0.761 seconds, Fetched: 1 row(s)
