> In testing on a cluster, I restarted with one fewer datanodes than
> previously. This caused a few thousand blocks to be under-replicated. Similar
> to HDFS-2795, I saw the under-replicated blocks on the SBN, slowly decreasing
> as the replication thread ran. This seems to be because we process the
> replication queue when exiting safemode, even if in standby mode. It also
> reports many "missing blocks" in the NN UI which are slowly decreasing.
