Mingliang Liu commented on HDFS-9129:
-------------------------------------
Thanks to [~anu] for the review and comment.
Anu and I are discussing the potential conflicts with [HDFS-4015] offline, and
I'll update the patch soon once we reach consensus.

I think it might be a good idea to move BytesInFutureBlocks also to the same
class.

Agreed. Let's address that separately as this jira is to move safemode block
count from {{FSNamesystem}} to {{BlockManager}}. I'll report this after this is
resolved, and invite you to review the work.

> The {{SafeMode}} needs to track whether there are enough blocks so that the
> NN can get out of the safemode. These fields can moved to the
> {{BlockManager}} class.
