disable your IPv6 settings..problem with IPv6 is that using 0.0.0.0 for various networking-related Hadoop configuration options will result in Hadoop binding to the IPv6 addresses..add the following lines at the end of your /etc/sysctl.conf -
net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1 net.ipv6.conf.lo.disable_ipv6 = 1 Regards, Mohammad Tariq On Mon, May 28, 2012 at 7:07 AM, Norbert Burger <[email protected]> wrote: > Looks like localhost is somehow resolving to an IPv6 address.
