Michał Michalski updated CASSANDRA-5302:
----------------------------------------
Description:
My pedantic nature can't stand having unaligned columns in nodetool outputs,
which happens when IP addresses are IPv6 ones:
{noformat}michal@aperture$ nodetool -h myhost status
Datacenter: DC1
==================
Status=Up/Down
|/ State=Normal/Leaving/Joining/Moving
-- Address Load Owns (effective) Host ID
Token Rack

{noformat}
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.
