> My pedantic nature can't stand having unaligned columns in nodetool outputs,
> which happens when IP addresses are IPv6 ones:

> cssa01-04.oslo.osa status
> Datacenter: DC1

> I'm attaching a patch that fixes this problem for nodetool status / ring
> commands. It does it by picking first item in nodes list (for nodetool ring
> it's first node in general, for nodetool status it's first node in each DC)
> and uses its length as a field length for output.
> It bases on assumptions that it's imppossible to have 0 nodes in cluster/DC
> and the lenghts of addresses are equal. Let me know if there's the case when
> it's not valid.
