Alejandro,
We're running Oozie server 2.3.2-cdh3u4.
The shell action appears to be supported based on the documentation,
but when I run my workflow, I get the following error in the oozie
logs:
E0701: XML schema error, cvc-complex-type.2.4.c: The matching
wildcard is strict, but no declaration can be found for element
'shell'.
When I use xmlns="uri:oozie:workflow:0.3" I get the following error:
XException, org.apache.oozie.command.CommandException: E0701: XML
schema error, cvc-elt.1: Cannot find the declaration of element
'workflow-app'.
org.apache.oozie.command.CommandException: E0701: XML schema error,
cvc-elt.1: Cannot find the declaration of element 'workflow-app'.
Here is m workflow.xml:
<workflow-app xmlns="uri:oozie:workflow:0.2" name="dlx-mapping-processor-main">
<start to="shell-test"/>
<action name="shell-test">
<shell xmlns="uri:oozie:shell-action:0.1">
<job-tracker>${jobTracker}</job-tracker>
<name-node>${nameNode}</name-node>
<configuration>
<property>
<name>mapred.job.queue.name</name>
<value>${queueName}</value>
</property>
</configuration>
<exec>pwd</exec>
<capture-output/>
</shell>
<ok to="end"/>
<error to="fail"/>
</action>
<kill name="fail">
<message>Node failed, error
message[${wf:errorMessage(wf:lastErrorNode())}]</message>
</kill>
<end name="end"/>
</workflow-app>
