Yi Liu commented on HDFS-8499:
------------------------------
Thanks Zhe for the work, the interfaces/classes hierarchy looks good overall.
In {{BlockInfoUnderConstruction}}, we can implement
{{addStorage/removeStorage/numNodes/replaceBlock}}, no need to push them to
subclass.
In {{BlockInfo}}, {{convertToBlockUnderConstruction}} should be abstract, and
continuous/striped block implement it.
> Merge BlockInfoUnderConstruction into trunk
