Ajay Yadava commented on FALCON-1342:
-------------------------------------

[~bvellanki] This change seems to address the duplicate property issue only in cluster entity. Any reason for not doing it for process and feed also?

> When specifying properties for a cluster, this is currently allowed,
> {code}
> <properties>
>         <property name="test" value="value1"/>
>         <property name="test" value="value2"/>
> </properties>
> {code}
> The propeties are stored as an array of org.apache.falcon.entity.v0.cluster.Property, and cluster.getProperty("test") will return either "value1" or "value2" but not both. If falcon does not support multiple values for same property key,  parsing such an entity should throw an error.
