Subject [jira] [Commented] (HDFS-2290) Block with corrupt replica is not getting replicated
Date Fri, 26 Aug 2011 23:51:29 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2290?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13092138#comment-13092138
] 

Konstantin Shvachko commented on HDFS-2290:
-------------------------------------------

Actually, in case (2) it does not get to deletion of meta-file. The block is not in the volume
map, but it is still reported by DN on block reports.

> A block has one replica marked as corrupt and two good ones. countNodes() correctly detects
that there are only 2 live replicas, and fsck reports the block as under-replicated. But ReplicationMonitor
never schedules replication of good replicas.
