Executing Sqoops using Oozie - hadoop

Question

I have 2 Sqoops that loads data from HDFS to MySQL. I want to execute them using Oozie. I have seen that Oozie is an XML file. How can I configure it so I can execute those Sqoop? Demonstration with steps will be appreciated?
Two Sqoops are:
1.
sqoop export --connect jdbc:mysql://localhost/hduser --table foo1 -m 1 --export-dir /user/cloudera/bar1
2.
sqoop export --connect jdbc:mysql://localhost/hduser --table foo2 -m 1 --export-dir /user/cloudera/bar2
Thanks.

You don't have to execute it via a shell action. There is a separate sqoop action in oozie. Here is what you have to put in your workflow.xml
<workflow-app xmlns="uri:oozie:workflow:0.4" name="oozie-wf">
<start to="sqoop-wf1"/>
<action name="sqoop-wf1">
<sqoop xmlns="uri:oozie:sqoop-action:0.2">
<job-tracker>${jobTracker}</job-tracker>
<name-node>${nameNode}</name-node>
<command>export --connect jdbc:mysql://localhost/hduser --table foo1 -m 1 --export-dir /user/cloudera/bar1</command>
</sqoop>
<ok to="sqoop-wf2"/>
<error to="fail"/>
</action>
<action name="sqoop-wf2">
<sqoop xmlns="uri:oozie:sqoop-action:0.2">
<job-tracker>${jobTracker}</job-tracker>
<name-node>${nameNode}</name-node>
<command>export --connect jdbc:mysql://localhost/hduser --table foo1 -m 1 --export-dir /user/cloudera/bar2</command>
</sqoop>
<ok to="end"/>
<error to="fail"/>
</action>
<kill name="fail">
<message>Failed, Error Message[${wf:errorMessage(wf:lastErrorNode())}]</message>
</kill>
<end name="end"/>
</workflow-app>
Hope this helps..

You can use an Oozie shell action for this. Basically you need to create a shell action & provide the commands that you posted in your question as the commands to be executed within the action
Sample Oozie action:
<action name="SqoopAction">
<shell xmlns="uri:oozie:shell-action:0.1">
<job-tracker>[JOB-TRACKER]</job-tracker>
<name-node>[NAME-NODE]</name-node>
<prepare>
<delete path="[PATH]"/>
...
<mkdir path="[PATH]"/>
...
</prepare>
<job-xml>[SHELL SETTINGS FILE]</job-xml>
<configuration>
<property>
<name>[PROPERTY-NAME]</name>
<value>[PROPERTY-VALUE]</value>
</property>
...
</configuration>
<exec>[SHELL-COMMAND]</exec>
<argument>[ARG-VALUE]</argument>
...
<argument>[ARG-VALUE]</argument>
<env-var>[VAR1=VALUE1]</env-var>
...
<env-var>[VARN=VALUEN]</env-var>
<file>[FILE-PATH]</file>
...
<archive>[FILE-PATH]</archive>
...
<capture-output/>
</shell>
In your case, you would replace [SHELL-COMMAND] with whatever Sqoop command you want to run, such as:
<exec>sqoop export --connect jdbc:mysql://localhost/hduser --table foo1 -m 1 --export-dir /user/cloudera/bar1</exec>
Also, you could put all your sqoop commands in a shell script, and execute that script instead. This is better if you have a lot of commands to be executed.
