[jira] [Commented] (CASSANDRA-3496) Load from `nodetool ring` does
not update after cleanup.
[ https://issues.apache.org/jira/browse/CASSANDRA-3496?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13150744#comment-13150744 ]
Jonathan Ellis commented on CASSANDRA-3496:
-------------------------------------------
Jackson pointed out that doing it in the current order, the data will be removed by the time we call length() on it:
{code}
. sstable.markCompacted();
sstable.releaseReference();
liveSize.addAndGet(-sstable.bytesOnDisk());
{code}

> Looks like each operation that adds and removes SSTables only adds to the total and doesn't remove the old sstables from the total size count.
