Tsz Wo Nicholas Sze commented on HDFS-7537: ------------------------------------------- > ..., I think changes in fsck should not influent "TestLeaseRecovery2.java" > tests, right? Agree. The failure of TestLeaseRecovery2 has nothing to do with the patch. > fsck is confusing when dfs.namenode.replication.min > 1 && missing replicas > && NN restart > ----------------------------------------------------------------------------------------- > > Key: HDFS-7537 > URL: https://issues.apache.org/jira/browse/HDFS-7537 > Project: Hadoop HDFS > Issue Type: Improvement > Components: namenode > Reporter: Allen Wittenauer > Assignee: GAO Rui > Attachments: HDFS-7537.1.patch, HDFS-7537.2.patch, Screen Shot > 2015-02-26 at 10.27.46.png, Screen Shot 2015-02-26 at 10.30.35.png, > dfs-min-2-fsck.png, dfs-min-2.png > > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
