Subject [jira] [Commented] (HDFS-2822) processMisReplicatedBlock incorrectly identifies under-construction blocks as under-replicated
Date Mon, 23 Jan 2012 18:06:40 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2822?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13191301#comment-13191301

Todd Lipcon commented on HDFS-2822:

I re-ran TestFileAppend4 locally and it passed. That test has been flaky in the past. The
findbugs warning is not new.

> When the NN processes mis-replicated blocks while exiting safemode, it considers under-construction
blocks as under-replicated, inserting them into the neededReplicationsQueue. This makes them
show up as corrupt in the metrics and UI momentarily, until they're pulled off the queue.
At that point, it realizes that they aren't in fact under-replicated, correctly. This affects
both the HA branch and trunk/23, best I can tell.
