Zhe Zhang updated HDFS-8728:
----------------------------
Attachment: HDFS-8728-HDFS-7285.02.patch
Uploading branch-based {{HDFS-8728-HDFS-7285.02.patch}} to address some of
Andrew's comments:
# Since the patch is already large, will leave the ideas of {{getOp}} and
saving reference in {{StripedBlockStorageOp}} as follow-ons.
# I filed HDFS-8784 to rename {{numNodes}}.
This patch basically makes necessary changes to merge trunk's {{BlockInfo}}
hierarchy back to HDFS-7285 branch (as well as adding the striped
counterparts). If we agree upon this direction I will create another patch to
replace all unnecessary usages of {{BIC}}, {{BIS}}, {{BIUCC}}, {{BIUCS}} with
{{BlockInfo}} and {{BlockInfoUC}}.
After reaching a conclusion here, I plan to update {{Merge-1}} to {{Merge-14}}
patches accordingly, and then rebase the HDFS-7285 branch to catch up with
trunk.
[~jingzhao] Could you share some advice here? Thanks!
