Also, since both the repaired and unrepaired > strategy instances are trying to compact the same sstables, there's a 1 > minute delay waiting for {{CompactionManager.waitForCessation}} to time out > before anything happens. > Here's the script I used to duplicate: > https://gist.github.com/bdeggleston/324f4f0df1b7273d8fd5 -- This message was sent by Atlassian JIRA (v6.3.4#6332)
