Zhe Zhang updated HDFS-8499:
----------------------------
Attachment: HDFS-8499.02.patch
Attaching new patch to address Yi's comment. The {{BlockInfoContiguousFeature}}
class is a helper with static method implementing the shared logic of
{{BIContiguous}} and {{BIContiguousUC}}.
This is basically a multi-inheritance problem. I had an offline discussion with
[~andrew.wang] to compare different options of solving this. One option is
demonstrated in the 02 patch. Another option is to keep the hierarchy in
HDFS-7285 branch, and convert shared UC logic into a feature ([~jingzhao] and I
also discussed this idea in an earlier meetup). I'll post a patch later today
to demonstrate that direction, and we can determine which one is cleaner.
