[jira] [Created] (KUDU-1535) Add rack awareness

Jean-Daniel Cryans created KUDU-1535:
----------------------------------------

             Summary: 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


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).
