@InterfaceAudience.Public @InterfaceStability.Unstable public abstract class NodeAttribute extends Object
Node Attribute is a kind of a label which represents one of the attribute/feature of a Node. Its different from node partition label as resource guarantees across the queues will not be maintained for these type of labels.
A given Node can be mapped with any kind of attribute, few examples are HAS_SSD=true, JAVA_VERSION=JDK1.8, OS_TYPE=WINDOWS.
 Its not compulsory for all the attributes to have value, empty string is the
 default value of the NodeAttributeType.STRING
 
Node Attribute Prefix is used as namespace to segregate the attributes.
