Daryn Sharp commented on HDFS-12886:
------------------------------------
Thanks for the ping, will make time to review in the next few days. Just based
on cursory read, agree recovery should be able to succeed regardless of min
replication. If the number of recovered/available replicas is less than desired
then it’s just under replicated. You can’t wait for min replicas when there
physically aren’t that many - think rack loss. Waiting only increases odds of
data loss. That said, rarely is anything easy to fix as it seems with block
management...
