> 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}}.
