Oozie workflow之Hive Action

1、将examples中的hive复制到oozie-apps目录下，并重命名

/opt/cdh5.14.2/oozie-4.1.0/oozie-apps/hive-select
[root@master hive-select]# ll
total 20
-rw-r--r-- 1 root root 1000 Aug  4 13:52 job.properties
-rw-r--r-- 1 root root  110 Aug  4 13:52 README
-rw-r--r-- 1 root root  966 Aug  4 13:52 script.q
-rw-r--r-- 1 root root 2003 Aug  4 13:52 workflow.xml
-rw-r--r-- 1 root root 2398 Aug  4 13:52 workflow.xml.security

2、在hive-select目录下创建目录lib,并将mysql-connector-java-5.1.27-bin.jar放到lib目录下

3、将hive中的配置hive-site.xml复制到hive-select目录下

4、job.properties

jobTracker=master.cdh.com:8032
queueName=default
oozieAppsRoot=user/root/oozie-apps
oozieDataRoot=user/root/oozie/datas

oozie.use.system.libpath=true

oozie.wf.application.path=${nameNode}/${oozieAppsRoot}/hive-select/workflow.xml
outputDir=hive-select/output

5、userinfo-script.sql

insert overwrite directory '${OUTPUT}'
select user_id,user_name from db_bbc.tb_user;

    <action name="hive-select-node">
        <hive xmlns="uri:oozie:hive-action:0.5">
            <job-tracker>${jobTracker}</job-tracker>

    <kill name="fail">
        <message>Hive failed, error message[${wf:errorMessage(wf:lastErrorNode())}]</message>
    </kill>
    <end name="end"/>
</workflow-app>

8、将 hive-select上传到hdfs

bin/hdfs dfs -put /opt/cdh5.14.2/oozie-4.1.0/oozie-apps/hive-select /user/root/oozie-apps

9、启动ozzie任务：

[root@master oozie-4.1.0]# bin/oozie job -oozie http://master.cdh.com:11000/oozie/ -config oozie-apps/hive-select/job.properties -run
job: 0000002-180805230543527-oozie-root-W

10、任务结束以及结果：

[root@master hadoop-2.6.0]# bin/hdfs dfs -text /user/root/oozie/datas/hive-select/output/0*
18/08/06 05:22:25 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
