Lukas Majercak commented on HDFS-12886:
---------------------------------------
One problem that we should create a JIRA for is having the client get the
minReplication from NN, because currently it just ignores it, and can happily
write to just 1 DN. But that still would not solve this issue, and it needs to
be decided whether minReplication should be ignored in this block recovery case.
