Subject Why can't you manage one node from another?
Date Wed, 07 Apr 2010 19:21:04 GMT
I have 3 nodes in the cluster, and
    bin/nodetool --host this-host-name ring
Works as expected, but
    bin/nodetool --host some-other-host ring

always throws this exception:

My hosts file looks like:

127.0.0.1       localhost
127.0.1.1       ec1

# The following lines are desirable for IPv6 capable hosts
::1     localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
