Appears to actually stem from code in DataNodeID which assumes it's safe to
append together (ipaddr + ":" + port) -- which is OK for IPv4 and not OK for
IPv6. NetUtils.createSocketAddr( ) assembles a Java URI object, which requires
the format proto://[2401:db00:1010:70ba:face:0:8:0]:50010
Patch will be posted shortly.
