------------------------------

             Summary: Introduce timeout mechanism for IP to rack resolution
                 Key: HBASE-12557
                 URL: https://issues.apache.org/jira/browse/HBASE-12557
             Project: HBase
          Issue Type: Improvement
            Reporter: Ted Yu


Config parameter, "hbase.util.ip.to.rack.determiner", determines the class which does IP to
rack resolution.
The actual resolution may be lengthy.

This JIRA is continuation of HBASE-12554 where a mock DNSToSwitchMapping is used for rack
resolution.
A timeout parameter, "hbase.ip.to.rack.determiner.timeout", is proposed whose value governs
the duration which RackManager waits before rack resolution is stopped.
