> Project: Hadoop HDFS

> Components: namenode

> If minimum replication is set to 2 or higher and some of those replicas are
> missing and the namenode restarts, it isn't always obvious that the missing
> replicas are the reason why the namenode isn't leaving safemode. We should
> improve the output of fsck and the web UI to make it obvious that the missing
> blocks are from unmet replicas vs. completely/totally missing.
