Subject [jira] [Commented] (HDFS-8728) Erasure coding: revisit and simplify BlockInfoStriped and INodeFile
Date Fri, 17 Jul 2015 16:43:05 GMT

    [ https://issues.apache.org/jira/browse/HDFS-8728?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14631561#comment-14631561

Zhe Zhang commented on HDFS-8728:

bq. We should simply cherrypick HDFS-8499 to the branch and then work on the additional change.
Otherwise, it is hard to merge the branch back to trunk since this and HDFS-8499 are going
to conflict with each other.
Thanks for the suggestion [~szetszwo]. However, after cherrypicking HDFS-8499 without changing
{{BIStriped}}, the branch won't compile and it will be hard to verify the conflict-resolving
changes. I think it's actually easier to review this {{BlockInfo}} change as a whole.

After finalizing this change I will rebase the branch against trunk. As you concerned there
will be conflicts because we have made HDFS-8499 changes in both places. But git should be
able to identify some of these; the rest shouldn't be too hard to handle.
