> Key: CASSANDRA-13738
> URL: https://issues.apache.org/jira/browse/CASSANDRA-13738
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Reporter: Jay Zhuang
> Assignee: Jay Zhuang
> Fix For: 2.2.x, 3.0.x, 3.11.x, 4.x

> For example, here is one of our cluster with about 500GB per node, but
> {{nodetool status}} shows far more load than it actually is and keeps
> increasing, restarting the process will reset the load, but keeps increasing
> afterwards:
> {noformat}
> Status=Up/Down
> |/ State=Normal/Leaving/Joining/Moving
> -- Address Load Tokens Owns (effective) Host ID
> Rack

> The root cause is if the SSTable index summary is redistributed (typically
> executes hourly), the updated SSTable size is added again.
