Walter Su commented on HDFS-8909:
---------------------------------

bq. Instead of keeping doing git rebase, maybe we should switch to git merge 
now. We can skip HDFS-8801 when merging trunk changes.
bq. "a small change in trunk can cause conflicts for rebasing large number of 
commits in the feature branch" --- quote from Jing Zhao 
\[[email protected]\] in common-dev mailing list.
Totally agree. HDFS-8801 is an example. HDFS-8909 just tries to merge some part 
from trunk to branch, which is no different from 'git merge'.

> HDFS-8801 converts {{BlockInfoUC}} as a feature. We should consolidate 
> {{BlockInfoContiguousUC}} and {{BlockInfoStripedUC}} logics to use this 
> feature.
