Hello,
I recently did the "Enabling virtual nodes on an existing production
cluster" procedure (
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.
Before, it showed only 1 token per node, now it shows 256 tokens per node
(output below). 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.
Is this expected behavior, or did I make any mistake during the procedure?
Cassandra version: 1.2.10
