oozie安装部署在hadoop2.50.0-CDH5.3.6
最近在这几天在搞伪分布式安装hue,在安装oozie的时候总是启动不了web界面，花了很长时间搞定，下面是安装oozie的步骤总结一下：
安装环境：
- centOS6.4
- Java JDK 1.7
- Maven
- hadoop-2.5.0-cdh5.3.6
- oozie-4.0.0-cdh5.3.6
- ext-2.2.zip
安装前注意事项
Download ExtJS library (it must be version 2.2)。
ExtJS版本必须是2.2版本
It is recommended to use a Oozie Unix user for the Oozie server.
推荐使用Oozie这个Linux用户。这个暂时不需要管
解压oozie
配置hadoop的core-site.xml
我们的Hadoop平台使用的是用户xusy，这里配置Hadoop代理用户也使用该用户，部署Oozie的主机名为xuxudede.com。修改Hadoop的配置文件core-site.xml，增加如下配置内容：
hadoop.proxyuser.root.hosts cloud61 hadoop.proxyuser.root.groups root
解压oozie-hadooplibs-4.0.0-cdh5.3.6.tar.gz
Expand the Oozie hadooplibs tar.gz in the same location
Oozie distribution tar.gz was expanded
特别注意：解压的目录要与oozie解压的路径相同，解压完成后会在oozie根目录下生成一个hadooplibs文件！！！
如图： 
创建libext目录
Create a libext/ directory in the directory where Oozie was expanded.
在oozie的根目录中创建libext目录。
如图： 
将hadoop相关的jar库文件拷贝到libext下面
拷贝hadooplibs/hadooplib-2.5.0-cdh5.3.6.oozie-4.0.0-cdh5.3.6下的jar包到libext/目录下
拷贝ext-2.2.zip到libext/目录下
如图： 
创建war包并加到tomcat里
$ bin/oozie-setup.sh prepare-war
重启hadoop进成，直到脱离安全模式
先stop namenode、datanode、resourcemanager、nodemanager、historyserver，然后再分别start。这里不再讲述！
把oozie根目录下oozie-sharelib-4.0.0-cdh5.3.6-yarn.tar.gz包解压并且放到hdfs上
运行命令如下：hdfs://xuxudede.com:9000是HDFS主机名加端口号!
$bin/oozie-setup.sh sharelib create -fs hdfs://xuxudede.com:9000 -locallib oozie-sharelib-4.0.0-cdh5.3.6-yarn.tar.gz
1. Oozie install
/etc/profile:
OOZIE_HOME=/home/hadoop/oozie-3.2.0-cdh4.1.2
$OOZIE_HOME//oozie-server/bin/catalina.sh:
JAVA_HOME=/usr/jdk6/jdk1.6.0_32
CATALINA_HOME=/home/cup/oozie-3.3.0-cdh4.2.1/oozie-server
$OOZIE_HOME/bin/oozie-setup.sh:
$oozie-setup.sh -extjs /home/hadoop/ext-2.2.zip -hadoop 0.20.200 $HADOOP_HOME
$oozie-setup.sh -extjs /home/hadoop/ext-2.2.zip -hadoop 2.0 $HADOOP_HOME
2. $OOZIE_HOME/bin/oozie-run.sh 启动oozie
5. oozie启动报找不到org/apache/hadoop/utils/ReflectionUtils类
将/home/hadoop/oozie-3.2.0-cdh4.1.2/libtools/*.jar copy to /home/hadoop/oozie-3.2.0-cdh4.1.2/oozie-server/webapps/oozie/WEB-INF/lib下
6. oozie启动报
REASON: org.apache.oozie.service.ServiceException: E0103: Could not load service classes, Schema 'SA' does not exist {SELECT t0.bean_type, t0.conf, t0.console_url, t0.cred, t0.data, t0.error_code, t0.error_message, t0.external_child_ids, t0.external_id, t0.external_status, t0.name, t0.retries, t0.stats, t0.tracker_uri, t0.transition, t0.type, t0.user_retry_count, t0.user_retry_interval, t0.user_retry_max, t0.end_time, t0.execution_path, t0.last_check_time, t0.log_token, t0.pending, t0.pending_age, t0.signal_value, t0.sla_xml, t0.start_time, t0.status, t0.wf_id FROM WF_ACTIONS t0 WHERE t0.bean_type = ? AND t0.id = ?} [code=30000, state=42Y07]
7. $OOZIE_HOME/bin/ooziedb.sh create -sqlfile oozie.sql -run
Validate DB Connection
DONE
Check DB schema does not exist
DONE
Check OOZIE_SYS table does not exist
DONE
Create SQL schema
DONE
Create OOZIE_SYS table
DONE
Oozie DB has been created for Oozie version '3.2.0-cdh4.1.2'
The SQL commands have been written to: oozie.sql
sql脚本保存到$OOZIE_HOME/bin/oozie.sql文件中.
8. oozie-site.xml:
8.
Error occurred during initialization of VM
Incompatible minimum and maximum heap sizes specified
oozie-env.sh:
export CATALINA_OPTS="$CATALINA_OPTS -Xms2g -Xmx4g"
8. $OOZIE_HOME/bin/oozie-run.sh 启动oozie
$OOZIE_HOME/bin/oozie-run.sh & 后台启动oozie
最新:
$oozied.sh run
$ jps
28945 Bootstrap
9. $OOZIE_HOME/bin/oozie admin -oozie http://192.168.101.122:11000/oozie -status
System mode: NORMAL 则表示已经成功
http://192.168.101.122:11000/oozie就能看到Oozie的管理界面
