Thanks Jing for the comment! Yes the {{replaceBlock}} logic is also different with striping.
Uploading new patch with the {{replaceBlock}} change.

> As second step of the cleanup, we should make {{BlockInfo}} an abstract class and merge
the subclass {{BlockInfoContiguous}} from HDFS-7285 into trunk. The patch should clearly separate
where to use the abstract class versus the subclass.
