Nate McCall created CASSANDRA-11955:
---------------------------------------
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).
