Alexey Serbin updated KUDU-1535:
--------------------------------
Labels: location-awareness rack-awareness (was: )
> Add rack awareness
> ------------------
>
> Key: KUDU-1535
> URL: https://issues.apache.org/jira/browse/KUDU-1535
> Project: Kudu
> Issue Type: New Feature
> Components: master
> Reporter: Jean-Daniel Cryans
> Assignee: Will Berkeley
> Priority: Major
> Labels: location-awareness, rack-awareness
> Fix For: 1.9.0
>
>
> Kudu currently doesn't have the concept of rack awareness, so any kind of rack failure can result in data loss (assuming that Kudu has tablet servers in multiple racks).
> This changes how the master picks hosts to send new tablets to, and we also need to implement a way for the master to map hostname names to racks (could be similar to Hadoop).
