Error while validating Oozie workflow?

Alexraj84 — Fri, 27 May 2016 18:08:26 GMT

I am getting the error while validating a workflow.

Error: E0701: XML schema error, /d/app/workflow.xml, org.xml.sax.SAXParseException; lineNumber: 49; columnNumber: 11; cvc-complex-type.2.3: Element 'shell' cannot have character [children], because the type's content type is element-only.

Here is the workflow.xml

Any help is much appreciated.

The error is in your first shell action "cutoff_values_table". You've got the letter "z" at the end of the line.

<argument>-t</argument>z

Remove it and the XML validates.

As an aside, if you want, you can make your workflow a bit smaller by reducing the number of <argument> tags. The contents of <argument> tags are space-delimited in the order that they are declared, so you could turn

<argument>-c</argument>
<argument>${value}</argument>

into

<argument>-c ${value}</argument>

for example.
