Rushabh S Shah commented on HDFS-8872: -------------------------------------- [~vinodkv]: Apologies for the trouble. Will take care next time. > 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 > > Namenode ui and metasave will not report a block as missing if the only > replica is on decommissioning/decomissioned node while 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)
