Subject [jira] Created: (CASSANDRA-1553) warn of imbalanced ranges in nodetool ring

warn of imbalanced ranges in nodetool ring

                 Key: CASSANDRA-1553
             Project: Cassandra
          Issue Type: Improvement
          Components: Tools
            Reporter: Jonathan Ellis
            Priority: Minor
             Fix For: 0.6.6, 0.7.0

I'd like to enhance nodetool ring to show the % of the token range that it is responsible
for according to the partitioner (that is, before considering replication).  For RandomParitioner
this is easy.  For OPP we can estimate using describe_splits.  I'd also like to issue a warning
if any node N has more than 25% more of the ring than another node M.

(The reason we need to use the range for this instead of load, is load may include an arbitrary
amount of data that no longer belongs to the node, pending removal by cleanup.)
