------------------------------------------
Target Version/s: 2.7.2
Fix Version/s: (was: 2.7.2)
[~shahrs87], FYI, you should use target-version for your intention. Fix-version
is set at commit time. I'm fixing this for now.
> 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.
