----------------------------------------
Hi [~leosun08] We typically backport from the newer branches to older branches.
The branch-2.8 is the oldest active branch. Would you please rebase on branch-2?
asflicense warning is false alarm. There are minor checkstyle warning that can
be cleaned easily. The findbugs warning looks fishy. Looking back in my
mailbox, the same warning came out a few times for branch-2. So probably
unrelated, but we should file a jira for that.
Suggest to update the jira summary, as this is essentially a reimplementation
of HDFS-8901 for replicated blocks. Hadoop 2 does not support EC, and so
there's no need to support striped blocks. How about "Reimplement HDFS-8901 for
replicated block positional read in branch-2"?
Do we need any test? Or is this purely an performance improvement and existing
tests cover it all?
> Backport HDFS-8901 Use ByteBuffer in striping positional read to branch-2.8.x
