5) 执行任务
$ bin/oozie job -oozie http://linux01:11000/oozie -config oozie-apps/shell/job.properties -run |
3、案例三:Oozie调度MapReduce任务
目标:使用Oozie调度MapReduce任务
分步执行:
1) 找到一个可以运行的mapreduce任务的jar包(可以用官方的,也可以是自己写的)
2) 拷贝官方模板到oozie-apps
$ cp -r examples/apps/map-reduce/ oozie-apps/ |
3) 测试一下wordcount在yarn中的运行
$ ~/modules/cdh/hadoop-2.5.0-cdh5.3.6/bin/yarn jar ~/modules/cdh/hadoop-2.5.0-cdh5.3.6/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.5.0-cdh5.3.6.jar wordcount /input/ /output/ |
4) 配置map-reduce任务的job.properties以及workflow.xml
job.properties
nameNode=hdfs://linux01:8020 jobTracker=linux02:8032 queueName=default examplesRoot=oozie-apps #hdfs://linux01:8020/user/admin/oozie-apps/map-reduce/workflow.xml oozie.wf.application.path=${nameNode}/user/${user.name}/${examplesRoot}/map-reduce/workflow.xml outputDir=map-reduce |
workflow.xml
<workflow-app xmlns="uri:oozie:workflow:0.2" name="map-reduce-wf"> <start to="mr-node"/> <action name="mr-node"> <map-reduce> <job-tracker>${jobTracker}</job-tracker> <name-node>${nameNode}</name-node> <prepare> <delete path="${nameNode}/output/"/> </prepare> <configuration> <property> <name>mapred.job.queue.name</name> <value>${queueName}</value> </property> <!-- 配置调度MR任务时,使用新的API --> <property> <name>mapred.mapper.new-api</name> <value>true</value> </property> <property> <name>mapred.reducer.new-api</name> <value>true</value> </property> <!-- 指定Job Key输出类型 --> <property> <name>mapreduce.job.output.key.class</name> <value>org.apache.hadoop.io.Text</value> </property> <!-- 指定Job Value输出类型 --> <property> <name>mapreduce.job.output.value.class</name> <value>org.apache.hadoop.io.IntWritable</value> </property> <!-- 指定输入路径 --> <property> <name>mapred.input.dir</name> <value>/input/</value> </property> <!-- 指定输出路径 --> <property> <name>mapred.output.dir</name> <value>/output/</value> </property> <!-- 指定Map类 --> <property> <name>mapreduce.job.map.class</name> <value>org.apache.hadoop.examples.WordCount$TokenizerMapper</value> </property> <!-- 指定Reduce类 --> <property> <name>mapreduce.job.reduce.class</name> <value>org.apache.hadoop.examples.WordCount$IntSumReducer</value> </property> <property> <name>mapred.map.tasks</name> <value>1</value> </property> </configuration> </map-reduce> <ok to="end"/> <error to="fail"/> </action> <kill name="fail"> <message>Map/Reduce failed, error message[${wf:errorMessage(wf:lastErrorNode())}]</message> </kill> <end name="end"/> </workflow-app> |
5) 拷贝待执行的jar包到map-reduce的lib目录下
$ cp -a ~/modules/cdh/hadoop-2.5.0-cdh5.3.6/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.5.0-cdh5.3.6.jar oozie-apps/map-reduce/lib |
6) 上传配置好的app文件夹到HDFS
$ ~/modules/cdh/hadoop-2.5.0-cdh5.3.6/bin/hdfs dfs -put oozie-apps/map-reduce/ /user/admin/oozie-apps |
7) 执行任务
$ bin/oozie job -oozie http://linux01:11000/oozie -config oozie-apps/map-reduce/job.properties -run |
4、案例四:Oozie定时任务/循环任务
目标:Coordinator周期性调度任务
分步实现:
1) 配置Linux时区以及时间服务器
注意这里,如果显示的时区不是+0800,你可以删除localtime文件夹后,再关联一个正确时区的链接过去,命令如下:
# rm -rf /etc/localtime # ln -s /usr/share/zoneinfo/Asia/Shanghai /etc/localtime |
同步时间:
修改NTP配置文件:
# vi /etc/ntp.conf 去掉下面这行前面的# ,并把网段修改成自己的网段: restrict 192.168.122.0 mask 255.255.255.0 nomodify notrap 注释掉以下几行: #server 0.centos.pool.ntp.org #server 1.centos.pool.ntp.org #server 2.centos.pool.ntp.org 把下面两行前面的#号去掉,如果没有这两行内容,需要手动添加 server 127.127.1.0 # local clock fudge 127.127.1.0 stratum 10 |
重启NTP服务:
# systemctl start ntpd.service, 注意,如果是centOS7以下的版本,使用命令:service ntpd start # systemctl enable ntpd.service, 注意,如果是centOS7以下的版本,使用命令:chkconfig ntpd on |
集群其他节点去同步这台时间服务器时间:
首先需要关闭这两台计算机的ntp服务 # systemctl stop ntpd.service, centOS7以下,则:service ntpd stop # systemctl disable ntpd.service, centOS7以下,则:chkconfig ntpd off # systemctl status ntpd,查看ntp服务状态 # pgrep ntpd,查看ntp服务进程id 同步第一台服务器linux01的时间: # ntpdate linux01 |
使用root用户制定计划任务,周期性同步时间:
# crontab -e */10 * * * * /usr/sbin/ntpdate linux01 |
重启定时任务:
# systemctl restart crond.service, centOS7以下使用:service crond restart, |
其他台机器的配置同理。
2) 配置oozie-site.xml文件
属性:oozie.processing.timezone 属性值:GMT+0800 解释:修改时区为东八区区时 |
尖叫提示:该属性去oozie-default.xml中找到即可
3) 修改js框架中的关于时间设置的代码
$ vi ~/modules/cdh/oozie-4.0.0-cdh5.3.6/oozie-server/webapps/oozie/oozie-console.js 修改如下: function getTimeZone() { Ext.state.Manager.setProvider(new Ext.state.CookieProvider()); return Ext.state.Manager.get("TimezoneId","GMT+0800"); } |
4) 重启oozie服务,并重启浏览器(一定要注意清除缓存)
$ bin/oozied.sh stop $ bin/oozied.sh start |
5) 拷贝官方模板配置定时任务
$ cp -r examples/apps/cron/ oozie-apps/ |
6) 修改模板job.properties和coordinator.xml以及workflow.xml
job.properties
nameNode=hdfs://linux01:8020 jobTracker=linux02:8032 queueName=default examplesRoot=oozie-apps oozie.coord.application.path=${nameNode}/user/${user.name}/${examplesRoot}/cron #start:必须设置为未来时间,否则任务失败 start=2017-07-29T17:00+0800 end=2017-07-30T17:00+0800 workflowAppUri=${nameNode}/user/${user.name}/${examplesRoot}/cron EXEC1=p1.sh EXEC2=p2.sh |
coordinator.xml
<coordinator-app name="cron-coord" frequency="${coord:minutes(5)}" start="${start}" end="${end}" timezone="GMT+0800" xmlns="uri:oozie:coordinator:0.2"> <action> <workflow> <app-path>${workflowAppUri}</app-path> <configuration> <property> <name>jobTracker</name> <value>${jobTracker}</value> </property> <property> <name>nameNode</name> <value>${nameNode}</value> </property> <property> <name>queueName</name> <value>${queueName}</value> </property> </configuration> </workflow> </action> </coordinator-app> |
workflow.xml
<workflow-app xmlns="uri:oozie:workflow:0.5" name="one-op-wf"> <start to="p3-shell-node"/> <action name="p3-shell-node"> <shell xmlns="uri:oozie:shell-action:0.2"> <job-tracker>${jobTracker}</job-tracker> <name-node>${nameNode}</name-node> <configuration> <property> <name>mapred.job.queue.name</name> <value>${queueName}</value> </property> </configuration> <exec>${EXEC3}</exec> <file>/user/admin/oozie-apps/cron/${EXEC3}#${EXEC3}</file> <!-- <argument>my_output=Hello Oozie</argument>--> <capture-output/> </shell> <ok to="end"/> <error to="fail"/> </action> <kill name="fail"> <message>Shell action failed, error message[${wf:errorMessage(wf:lastErrorNode())}]</message> </kill> <kill name="fail-output"> <message>Incorrect output, expected [Hello Oozie] but was [${wf:actionData('shell-node')['my_output']}]</message> </kill> <end name="end"/> </workflow-app> |
7) 上传配置
$ ~/modules/cdh/hadoop-2.5.0-cdh5.3.6/bin/hdfs dfs -put oozie-apps/cron/ /user/admin/oozie-apps |
8) 启动任务
$ bin/oozie job -oozie http://linux01:11000/oozie -config oozie-apps/cron/job.properties -run |
尖叫提示:oozie允许的最小执行任务的频率是5分钟
