Jackson Chung commented on CASSANDRA-3220:
------------------------------------------
ok, i have done a nodetool version. most of the thing work.. except somehow
jconsole/jmxterm doesn't. First the nodetool output:
$ nodetool -h zaranth -p 8199 describering Keyspace1
TokenRange:
TokenRange(start_token:0,
end_token:56713727820156410577229101238628035242, endpoints:[184.106.233.162],
rpc_endpoints:[184.106.233.162],
endpoint_details:[EndpointDetails(host:184.106.233.162, datacenter:datacenter1,
rack:rack1)])
TokenRange(start_token:56713727820156410577229101238628035242,
end_token:113427455640312821154458202477256070485, endpoints:[184.106.203.196],
rpc_endpoints:[184.106.203.196],
endpoint_details:[EndpointDetails(host:184.106.203.196, datacenter:datacenter1,
rack:rack1)])
TokenRange(start_token:113427455640312821154458202477256070485,
end_token:0, endpoints:[184.106.204.143], rpc_endpoints:[184.106.204.143],
endpoint_details:[EndpointDetails(host:184.106.204.143, datacenter:datacenter1,
rack:rack1)])
$nodetool -h zaranth -p 8199 describering
Missing keyspace argument for describering.
usage: java org.apache.cassandra.tools.NodeCmd --host <arg> <command>
...
$ nodetool -h zaranth -p 8199 describering system
There is no ring for the keyspace: system
usage: java org.apache.cassandra.tools.NodeCmd --host <arg> <command>
...
$ nodetool -h zaranth -p 8199 describering thisdoesnotexist
There is no ring for the keyspace: thisdoesnotexist
usage: java org.apache.cassandra.tools.NodeCmd --host <arg> <command>
now the problem with jconsole/jmxterm:
