> The default value of config: sun.net.inetaddr.ttl is -1 and the java processes will cache
the mapping of hostname to ip address  forever, See: http://docs.oracle.com/javase/7/docs/technotes/guides/net/properties.html
> But things go wrong when a regionserver with same hostname and different ip address rejoins
the hbase cluster. The HMaster will get wrong ip address of the regionserver from this cache
and every region assignment to this regionserver will be blocked for a time because the HMaster
can't communicate with the regionserver.
> A tradeoff is to set the sun.net.inetaddr.ttl to 10m or 1h and make the wrong cache expired.
> Suggestions are welcomed. Thanks~
