> Per discussion under HDFS-8499, with the erasure coding feature, there will 
> be 4 types of {{BlockInfo}} forming a multi-inheritance: 
> {{complete+contiguous}}, {{complete+striping}}, {{UC+contiguous}}, 
> {{UC+striped}}. We had the same challenge with {{INodeFile}} and the solution 
> was building feature classes like {{FileUnderConstructionFeature}}. This JIRA 
> aims to implement the same idea on {{BlockInfo}}.
