Rushabh S Shah created HDFS-8872: ------------------------------------ Summary: Reporting of missing blocks is different in fsck and namenode ui/metasave Key: HDFS-8872 URL: https://issues.apache.org/jira/browse/HDFS-8872 Project: Hadoop HDFS Issue Type: Bug Affects Versions: 2.6.0 Reporter: Rushabh S Shah Assignee: Rushabh S Shah Fix For: 2.7.2
Namenode ui and metasave will not report a block as missing if the only replica is on decommissioning/decomissioned node where fsck will show it as MISSING. Since decommissioned node can be formatted/removed anytime, we can actually lose the block. Its better to alert on namenode ui if the only copy is on decomissioned/decommissioning node. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
