---------------------------------------

             Summary: Impossibly large value displayed for data "load" and "Space used (total):"
                 Key: CASSANDRA-11955
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-11955
             Project: Cassandra
          Issue Type: Bug
          Components: Compaction
            Reporter: Nate McCall


The data load as reported by nodetool views looks like it is not getting updated correctly (from compaction?):

NOTE: unknown if the join is related as the "TB" vs. "GB" discrepancy was only noticed after the join started.

And same for {{nodetool tablestats}} details of the {{30531bfe...}} node:

Nothing fancy on this table (there is only one active table on this cluster): STCS with defaults, no MVs, no indexes just text and int columns with a single value partition key. 

NOTE: once restarted, the values then display as correct, creeping up from there (thus my thinking that this is a compaction issue).
