Description
In Spark Action 0.1 schema, the job-tracker and name-node are required.
<xs:element name="job-tracker" type="xs:string" minOccurs="1" maxOccurs="1"/> <xs:element name="name-node" type="xs:string" minOccurs="1" maxOccurs="1"/>
It would be better that the spark action can take default values from the global configs.
