Description

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.
