Subject Re: Output of "nodetool ring" with virtual nodes
Date Tue, 15 Oct 2013 18:50:52 GMT
It's expected.  I think nodetool status is meant to replace nodetool ring.

(http://www.datastax.com/documentation/cassandra/1.2/webhelp/cassandra/configuration/configVnodesProduction_t.html),
and noticed that the output of the command "nodetool ring" changes significantly when virtual
nodes are enabled in a new data center.

So, that means 256*N entries, which makes the command unreadable, while before it was pretty
useful to check the cluster status in a human-readable format. Moreover, the command is taking
much longer to execute.
