A replication storm ensues possibly causing DNs to > temporarily go dead (HDFS-12645), leading to more FBR lease rejections on > re-registration. The cluster will have many "missing blocks" until the DNs > next FBR is sent and/or forced. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
