To be clear, we are running 2.8 and 2.10. Although we don't see any issues,
I am curious whether the change in heap usage is amplified on dense
datanodes.

Which layout change are you referring to? The only layout change I know of
was done in 2.7, IIRC. We backported that to 2.6 and did not see any
adverse effects at that time.
Is datanode using more heap all the time? Or is it running into trouble
when generating full block reports?

On Mon,
Gabor,
If you want to release asap, you can simply revert HDFS-14941 in the
release branch for now. It is causing the issue and was committed after
3.1.3. This causes failure of the automated upgrade process and namenode
memory leak.

Thanks for driving the next 2.8 release, Junping. While I was committing a
blocker for 2.7.4, I noticed some of the jiras are back-ported to 2.7, but
missing in branch-2.8.2. Perhaps it is safer and easier to simply rebranch
2.8.2.
