一、环境

maven-3.3.0

hadoop-2.7.1

二、编译

[root@hftclclw0001 opt]# pwd
/opt

[root@hftclclw0001 opt]# wget http://apache.mirrors.pair.com/oozie/4.1.0/oozie-4.1.0.tar.gz
[root@hftclclw0001 opt]# tar -zxvf  oozie-4.1.0.tar.gz
[root@hftclclw0001 opt]# cd oozie-4.1.0

#默认
#sqoop.version=1.4.3 
#hive.version=0.13.1     => 修改为其他，编译出错
#hbase.version=0.94.2    => 修改为其他，编译出错
#pig.version=0.12.1 
#hadoop.version=2.3.0    => 最新版本是2.3.0 但是支持2.7.1
#tomcat.version=6.0.43
[root@hftclclw0001 opt]# ./bin/mkdistro.sh -DskipTests -Phadoop-2  -Dsqoop.version=1.4.6
...
...
...
INFO] BUILD SUCCESS

Oozie distro created, DATE[2016.06.19-12:38:39GMT] VC-REV[unavailable], available at [/opt/oozie-4.1.0/distro/target]

三、配置

[root@hftclclw0001 opt]# pwd
/opt

[root@hftclclw0001 opt]# mkdir Oozie
[root@hftclclw0001 opt]# cd Oozie

[root@hftclclw0001 Oozie]# pwd
/opt/Oozie

[root@hftclclw0001 Oozie]# cp ../oozie-4.1.0/distro/target/oozie-4.1.0-distro.tar.gz ./
[root@hftclclw0001 Oozie]# tar -zxvf oozie-4.1.0-distro.tar.gz
[root@hftclclw0001 Oozie]# cd oozie-4.1.0
[root@hftclclw0001 oozie-4.1.0]# pwd
/opt/Oozie/oozie-4.1.0

[root@hftclclw0001 oozie-4.1.0]# mkdir libext
[root@hftclclw0001 oozie-4.1.0]# cp /opt/oozie-4.1.0/hadooplibs/hadoop-2/target/hadooplibs/hadooplib-2.3.0.oozie-4.1.0/* ./libext
[root@hftclclw0001 oozie-4.1.0]# cd libext

[root@hftclclw0001 libext]# curl -O http://archive.cloudera.com/gplextras/misc/ext-2.2.zip

下载MySQL驱动放入libext，因为用mysql作为元数据库，默认为Derby
[root@hftclclw0001 libext]# ll
total 26452
...
-rw------- 1 root root  848401 Jun 19 13:41 mysql-connector-java-5.1.25-bin.jar
...

[root@hftclclw0001 libext]# cd ..
[root@hftclclw0001 oozie-4.1.0]# pwd
/opt/Oozie/oozie-4.1.0

[root@hftclclw0001 oozie-4.1.0]# ./bin/oozie-setup.sh prepare-war

[root@hftclclw0001 oozie-4.1.0]# ./bin/oozie-setup.sh sharelib create -fs hdfs://localhost:9000


创建Oozie数据库
[root@hftclclw0001 oozie-4.1.0]# mysql -uroot -p


mysql>CREATE DATABASE OOZIEDB;
mysql>GRANT ALL PRIVILEGES ON OOZIEDB.* TO oozie IDENTIFIED BY "oozie";
mysql>FLUSH PRIVILEGES;


配置conf/oozie-site.xml
oozie.service.JPAService.jdbc.driver
oozie.service.JPAService.jdbc.url
oozie.service.JPAService.jdbc.username
oozie.service.JPAService.jdbc.password

[root@hftclclw0001 oozie-4.1.0]# ./bin/ooziedb.sh create db -run


配置etc/hadoop/core-site.xml，配置oozie的proxyuser

   hadoop.proxyuser.$USER.hosts
   *


   hadoop.proxyuser.$USER.groups
   */value>


$USER替换为oozie service的用户，或oozie，或root等

[root@hftclclw0001 oozie-4.1.0]# ./oozied.sh start

四、examples

job.properties

nameNode=hdfs://nameservice1
#nameNode=hdfs://nameservice1 ==> HA
#nameNode=hdfs://${namenode}:8020 ==> single namenode

jobTracker=dapdevhmn001.qa.webex.com:8032
#jobTracker=rm1,rm2 ==> HA
#jobTracker(yarn.resourcemanager.address)=10.224.243.124:8032
queueName=default
examplesRoot=examples
#oozie.use.system.libpath=true

oozie.wf.application.path=${nameNode}/user/${user.name}/${examplesRoot}/apps/map-reduce
outputDir=map-reduce

workflow.xml

    
    
        
            ${jobTracker}
            ${nameNode}
            
                
            
            
                
                    mapred.job.queue.name
                    ${queueName}
                
                
                    mapred.mapper.class
                    org.apache.oozie.example.SampleMapper
                
                
                    mapred.reducer.class
                    org.apache.oozie.example.SampleReducer
                
                
                    mapred.map.tasks
                    1
                
                
                    mapred.input.dir
                    /user/${wf:user()}/${examplesRoot}/input-data/text
                
                
                    mapred.output.dir
                    /user/${wf:user()}/${examplesRoot}/output-data/${outputDir}
                
            
        
        
        
    
    
        Map/Reduce failed, error message[${wf:errorMessage(wf:lastErrorNode())}]
    
    

lib/oozie-examples-4.1.0.jar

hadoop fs -mkdir -p /user/root/examples/apps/map-reduce

hadoop fs -put ./job.properties /user/root/examples/apps/map-reduce

hadoop fs -put ./workflow.xml /user/root/examples/apps/map-reduce

hadoop fs -put ./lib/oozie-examples-4.1.0.jar /user/root/examples/apps/map-reduce

job.properties ==> 不仅仅需要在HDFS，本地也需要一份。执行命令-config是指向本地的文件

oozie job -oozie ${OOZIE_URL} -config job.properties-run

oozie job -oozie ${OOZIE_URL} -info ${oozie_id}

#oozie job -oozie ${OOZIE_URL} -info 0000001-170206083712434-oozie-oozi-W

oozie job -oozie ${OOZIE_URL} -log ${oozie_id}

#oozie job -oozie ${OOZIE_URL} -log 0000001-170206083712434-oozie-oozi-W

五、distcp

job.properties

nameNode=hdfs://${sourceNameNode}:8020
destNameNode=hdfs://${destNameNode}:8020
jobTracker=${RM}:8032
#yarn.resourcemanager.address=${RM}:8032
queueName=default
examplesRoot=examples
oozie.use.system.libpath=true

oozie.wf.application.path=${nameNode}/user/${user.name}/${examplesRoot}/apps/distcp_2
outputDir=distcp

workflow.xml

    
    
        
            ${jobTracker}
            ${nameNode}
            
                
            
            
                
                    mapred.job.queue.name
                    ${queueName}
                
            
            ${nameNode}/user/${wf:user()}/${examplesRoot}/input-data/text/data.txt
            ${destNameNode}/tmp/data.txt
            
        
        
    
    
        DistCP failed, error message[${wf:errorMessage(wf:lastErrorNode())}]
