大数据基础之Oozie（2）使用

命令行

$ oozie help

1 导出环境变量

$ export OOZIE_URL=http://oozie_server:11000/oozie

否则都需要增加 -oozie 参数，比如

$ oozie jobs -oozie http://oozie_server:11000/oozie

2 查看全部流程

$ oozie jobs

3 操作一个流程

$ oozie job
Invalid sub-command: Missing required option: [-suspend suspend a job, -resume resume a job, -dryrun Dryrun a workflow (since 3.3.2) or coordinator (since 2.0) job without actually executing it, -submit submit a job, -log job log, -change change a coordinator or bundle job, -start start a job, -update Update coord definition and properties, -run run a job, -poll poll Oozie until a job reaches a terminal state or a timeout occurs, -kill kill a job (coordinator can mention -action or -date), -configcontent job configuration, -rerun rerun a job (coordinator requires -action or -date, bundle requires -coordinator or -date), -ignore change status of a coordinator job or action to IGNORED (-action required to ignore coord actions), -definition job definition, -info info of a job]

3.1 查看一个流程的信息

$ oozie job -info 0000003-190315230448327-oozie-oozi-W

3.2 查看一个流程的日志

$ oozie job -log 0000003-190315230448327-oozie-oozi-W

3.3 查看一个流程的定义（xml）

$ oozie job -definition 0000003-190315230448327-oozie-oozi-W

3.4 查看一个流程的配置（properties）

$ oozie job -configcontent 0000003-190315230448327-oozie-oozi-W

示例流程

1 流程定义

执行系统命令

$ cat test_sh.xml
<workflow-app name="test_sh" xmlns="uri:oozie:workflow:0.5">
    <start to="test_sh_action"/>
    <kill name="Kill">
        <message>Action failed, error message[${wf:errorMessage(wf:lastErrorNode())}]</message>
    </kill>
    <action name="test_sh_action">
        <shell xmlns="uri:oozie:shell-action:0.1">
            <job-tracker>${jobTracker}</job-tracker>
            <name-node>${nameNode}</name-node>
            <exec>/usr/bin/df -h</exec>
            <capture-output/>
        </shell>
        <ok to="End"/>
        <error to="Kill"/>
    </action>
    <end name="End"/>
</workflow-app>

注意：df必须用绝对路径/usr/bin/df，因为action执行时没有环境变量PATH，或者执行 source /etc/profile &&df -h ;

 

执行sh脚本

<workflow-app name="test_sh_wf" xmlns="uri:oozie:workflow:0.5">
    <start to="test_sh_action"/>
    <kill name="Kill">
        <message>Action failed, error message[${wf:errorMessage(wf:lastErrorNode())}]</message>
    </kill>
    <action name="test_sh_action">
        <shell xmlns="uri:oozie:shell-action:0.1">
            <job-tracker>${jobTracker}</job-tracker>
            <name-node>${nameNode}</name-node>
            <exec>${script_file}</exec>
            <file>${script_file}</file>
            <capture-output/>
        </shell>
        <ok to="End"/>
        <error to="Kill"/>
    </action>
    <end name="End"/>
</workflow-app>

此时配置文件中需要定义

script_file=test_sh.sh

注意：test_sh.sh也要上传到hdfs上，与xml在一起，不能使用本地文件系统路径；

2 校验

$ oozie validate test_sh.xml

3 上传到hdfs

$ hdfs dfs -put test_sh.xml /user/oozie/wf/

4 配置文件

$ cat test_sh.properties
nameNode=hdfs://namenode:9000
jobTracker=resourcemanager:8032
oozie.wf.application.path=/user/oozie/wf/test_sh.xml

5 运行流程

$ oozie job -config test_sh.properties -run

6 其他

kill、rerun等，rerun的时候需要指定两个参数之一，即跳过指定的节点或者重跑失败的节点；

Missing configuration property [oozie.wf.rerun.skip.nodes OR oozie.wf.rerun.failnodes]

$ oozie job -Doozie.wf.rerun.failnodes=true -rerun 0000000-190329232917986-oozie-oozi-W
