Oozie integrated shell

1) prepare shell case
$ cd ~/work/oozie-5.2.1
$ tree oozie/apps/shell

oozie/apps/shell
├── hello.sh
├── job.properties
└── workflow.xml

$ cat oozie/apps/shell/hello.sh

#!/bin/sh

echo "my_output=Hello Oozie"

$ cat oozie/apps/shell/job.properties

nameNode=hdfs://localhost:9000
resourceManager=localhost:8032
queueName=default
oozieRoot=user/${user.name}/oozie

oozie.wf.application.path=${nameNode}/${oozieRoot}/apps/shell
EXEC=hello.sh

$ cat oozie/apps/shell/workflow.xml

<workflow-app xmlns="uri:oozie:workflow:1.0" name="shell-wf">
    <start to="shell-node"/>
    <action name="shell-node">
        <shell xmlns="uri:oozie:shell-action:1.0">
            <resource-manager>${resourceManager}</resource-manager>

                </property>
            </configuration>
            <exec>${EXEC}</exec>

            <capture-output/>
        </shell>
        <ok to="check-output"/>
        <error to="fail"/>
    </action>
    <decision name="check-output">
        <switch>
            <case to="end">
                ${wf:actionData('shell-node')['my_output'] eq 'Hello Oozie'}
            </case>
            <default to="fail-output"/>
        </switch>
    </decision>
    <kill name="fail">
        <message>Shell action failed, error message[${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>

2) upload to hdfs
$ hdfs dfs -put oozie/apps/shell oozie/apps/

3) run and check
$ bin/oozie job -config oozie/apps/shell/job.properties -run
job: 0000004-220629164930563-oozie-sun_-W
$ bin/oozie job -info 0000004-220629164930563-oozie-sun_-W

Note:
Shell action’s stdout and stderr output are redirected to the Oozie Launcher map-reduce job task STDOUT that runs the shell command
The output can be found under hdfs://localhost:9000/tmp/sun_xo/logs/application_1656492227290_0007/ 
application_1656492227290_0007 is ext_id of shell-node
