> Per offline discussion with [~andrew.wang], for easier and cleaner reviewing, we should
probably shrink the size of the consolidated HDFS-7285 patch by merging some mechanical changes
that are unrelated to EC-specific logic to trunk first. Those include renaming, subclassing,
interfaces, and so forth. This umbrella JIRA specifically aims to merge code changes around
{{BlockInfo}} and {{BlockInfoContiguous}} back into trunk.
> The structure of {{BlockInfo}} -related classes are shown below:
> {code}
>                 BlockInfo (abstract)
>                /         \
> BlockInfoStriped          BlockInfoContiguous
>        |                        |
>        |       BlockInfoUC      |
>        |       (interface)      |
>        |       /         \      |
> BlockInfoStripedUC       BlockInfoContiguousUC
> {code}
