Zhe Zhang commented on HDFS-8835:
---------------------------------
Thanks for sharing the feedback [~szetszwo].
HDFS-8487 (as well as HDFS-8653, HDFS-8605) just try to divide-and-conquer the
(inevitable) inconvenience for the community to understand and accept the EC
change. I feel this way is easier than absorbing the huge change all at once.
As shown below (copied from HDFS-8728 [discussion |
https://issues.apache.org/jira/browse/HDFS-8728?focusedCommentId=14619043&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14619043])
the overall EC change becomes much smaller and less intrusive after pushing
these changes to trunk first (I will do the rebase after HDFS-8499 revert).
{code}
Current HDFS-7285:
2532 insertions(+), 1156 deletions(-) in blockmanagement
1826 insertions(+), 444 deletions(-) in namenode
Rebased:
1251 insertions(+), 201 deletions(-) in blockmanagement
1324 insertions(+), 168 deletions(-) in namenode
{code}
That said, I understand that git rebasing is a relatively new workflow and
people have different preferences in absorbing changes. So more feedbacks are
very welcome.
