Allen Wittenauer created HDFS-7537:
--------------------------------------
Summary: dfs.namenode.replication.min > 1 && missing replicas &&
NN restart is confusing
Key: HDFS-7537
URL: https://issues.apache.org/jira/browse/HDFS-7537
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Allen Wittenauer
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
improving the output of fsck and the web UI to make it obvious that the missing
blocks are from unmet replicas vs. completely/totally missing.
