-----------------------------------------
Component/s: Stress
> cosmetic issue with compaction-stress write
> -------------------------------------------
>
> Key: CASSANDRA-12596
> URL: https://issues.apache.org/jira/browse/CASSANDRA-12596
> Project: Cassandra
> Issue Type: Bug
> Components: Stress
> Reporter: Wei Deng
> Priority: Minor
>
> I got the following when I was trying to run `compaction-stress write` with a
> 10GB data set. Looks like a race condition with the lifecycle transaction log
> but it only affects the reporting of the progress temporarily.
> {noformat}
> Written 50.27GB of 100GB
> ERROR 23:49:55,843 Error while getting
> /mnt/compaction/stresscql/blogposts-606839b5bd683964ad7f57f519eb6dae folder

> You will see the next "Written xxxGB" number being inaccurate because it
> interrupted the directory accounting of the data files, but the subsequent
> "Written xxxGB" number will get back to normal.
> Since it generates a ERROR log entry it's probably still worthwhile to fix.
