Zhe Zhang commented on HDFS-8608:
---------------------------------
[~szetszwo]: To help track original dev history I can list all JIRA numbers
contributing to a sub-patch. For example:
{code}
HDFS-7285 patch 2: Support Erasure Coding Zones. Including HDFS-7839,
HDFS-8077, HDFS-8444, and HDFS-8450.
{code}
Practically, at this stage it's pretty hard to rebase without squashing.
Especially in big classes like {{BlockManager}} and {{FSNamesystem}}. If we do
straightforward rebase, each trunk change will go through many branch commits.
We'll be making a lot of unnecessary conflict-resolving changes, on codes that
are overwritten by later commits.
> Merge HDFS-7912 to trunk and branch-2 (track BlockInfo instead of Block in
> UnderReplicatedBlocks and PendingReplicationBlocks)
