Jonathan Ellis commented on CASSANDRA-3220: ------------------------------------------- bq. it seems like i cannot return any object coming from thrift in the jmx Odd -- it *should* work since Thrift objects implement Serializable, but then again, it doesn't totally shock me that you're running into problems since that's definitely not a common use case. bq. Maybe I should make the jmx method to return a String (List of String?) instead? That's probably the best solution. We already prefer to avoid non-primitive types over JMX (CASSANDRA-2805). > add describe_ring to cli > ------------------------ > > Key: CASSANDRA-3220 > URL: https://issues.apache.org/jira/browse/CASSANDRA-3220 > Project: Cassandra > Issue Type: Improvement > Components: Tools > Reporter: Jackson Chung > Assignee: Jackson Chung > Priority: Minor > Fix For: 1.0.4 > > Attachments: patch3220.diff, patch3220.v2.diff, patch3220.v3.diff, > patch3220.v4.diff > > > Lately I have found the describe_ring feature was needed to debug/analyze > issue, but the cli does not have this available. > So just in case it is useful, please see the attached patch. > here is the sample output: > {noformat} > [default@unknown] help; > ... > ... > decr Decrements a counter column. > describe ring Describe the token range information. > describe cluster Describe the cluster configuration. > ... > ... > [default@unknown] help describe ring; > describe ring <keyspace>; > Describes the token range settings for the named keyspace. > Required Parameters: > - keyspace: Name of the keyspace to describe the token range. > Examples: > describe ring <keyspace>; - Describes the token range settings for the named > keyspace. > [default@unknown] describe ring Keyspace3; > TokenRange: > TokenRange(start_token:9739248273232290250409572410247679660, > end_token:9739248273232290250409572410247679660, endpoints:[192.168.0.125], > rpc_endpoints:[192.168.0.125], > endpoint_details:[EndpointDetails(host:192.168.0.125, port:9160, > datacenter:168)]) > [default@unknown] describe ring fooks; > Keyspace with name 'fooks' wasn't found, , please, authorize to one of the > keyspaces first. > [default@unknown] describe ring; > Syntax error at position 13: mismatched input ';' expecting set null > {noformat} -- This message is automatically generated by JIRA.
