Zhe Zhang updated HDFS-8487:
----------------------------
Description:
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}
