RegionServers go down when change hbase.regionserver.dns.interface

New Contributor

I tried setting hbase.regionserver.dns.interface --> eth1, but I'm getting this error as on the regionservers

I have seen that when you are working with ipv6, you can find this error. Because they use a split of ipv4,


            String[] parts = address.getHostAddress().split("\\.");
            String reverseIP = parts[3] + "." + parts[2] + "." + parts[1] + "."
                      + parts[0] + ".in-addr.arpa";


I have found a posible solution. Put this in the hadoop-env.cmd, but i cant test yet.


-Djava.net.preferIPv4Stack=true
