Jackson Chung updated CASSANDRA-3220:
-------------------------------------
Attachment: patch3220.v5.diff
ok, converting the methods on the jmx to return a list of String instead then.
PS: i've tried to use guava Lists.transform, but that fails with the following

{noformat}
so sticking with just simply manually convert.
result from jmx:
{noformat}
$>run describeRing Keyspace1
#calling operation describeRing of mbean
org.apache.cassandra.db:type=StorageService
#operation returns:
( TokenRange(start_token:0, end_token:0, endpoints:[192.168.11.6],
rpc_endpoints:[192.168.11.6],
endpoint_details:[EndpointDetails(host:192.168.11.6, datacenter:168, rack:11)])
)
{noformat}
the code using guava's Lists.transfrom is still there, please feel free to take
a look to see if i did some stupid mistake
