When I run a nodetool ring, I see a very uneven load. Any idea what I could be going on? I have not added/removed any nodes or changed the replication scheme or counts. </p> <p>Thanks!</p> <p>Address DC Rack Status State Load Effective-Ownership Token<br /> 113427455640312821154458202477256070485<br /> 10.56.92.194 WDC RAC1 Up Normal 53.65 GB 66.67% 0<br /> 10.28.91.10 SEA RC1 Up Normal 3.96 GB 66.67% 1<br /> 10.56.92.196 WDC RAC1 Up Normal 673.78 MB 66.67% 56713727820156410577229101238628035242<br /> 10.28.91.8 SEA RC1 Up Normal 670 MB 66.67% 56713727820156410577229101238628035243<br /> 10.56.92.198 WDC RAC1 Up Normal 746.25 MB 66.67% 113427455640312821154458202477256070484<br /> 10.28.91.2 SEA RC1 Up Normal 799.51 MB 66.67% 113427455640312821154458202477256070485 </p> <p>Replication Strategy: org.apache.cassandra.locator.NetworkTopologyStrategy<br /> Durable Writes: true<br /> Options: [WDC:2, SEA:2]</p> <p>Cluster Information:<br /> Snitch: org.apache.cassandra.locator.PropertyFileSnitch<br /> Partitioner: org.apache.cassandra.dht.RandomPartitioner</p> <p>##### WDC<br /> 10.56.92.194=WDC:RAC1<br /> 10.56.92.196=WDC:RAC1<br /> 10.56.92.198=WDC:RAC1</p> <p>#### SEATTLE<br /> 10.28.91.10=SEA:RC1<br /> 10.28.91.8=SEA:RC1<br /> 10.28.91.2=SEA:RC1</p> <p># default for unknown nodes<br /> default=DALLAS:RAC1 </p>
