Jackson Chung commented on CASSANDRA-3220:
------------------------------------------
working on the "unexpected block data"
it seems like i cannot return any object coming from thrift in the jmx
(./interface/thrift/gen-java/org/apache/cassandra/thrift/*)
I tried by creating a test method that simply return a TokenRange, a KeyRange,
an EndpointDetails in the StorageServiceMBean (return new <the object>())
Is there a restriction on that?
Maybe I should make the jmx method to return a String (List of String?) instead?
