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

Yep, after applying this [patch|https://issues.apache.org/jira/secure/attachment/12824146/0001-Replaced-using-CFMetaData.compile-in-cassandra-stres.patch], I was able to get {{compaction-stress write}} to work.

To apply the patch cleanly, the additional import packages needed to be manually inserted but it was trivial.

> When I was trying the new compaction-stress tool from 3.10, I ran into the following error:
> {noformat}

> [UPDATE] It appears that {{compaction-stress compact}} fails on the same assert but via a totally different code path. The stack trace is like the following:
> {noformat}
> automaton@0ce59d338-1:~/cassandra-trunk$ ./tools/bin/compaction-stress compact -d /tmp/compaction -p https://gist.githubusercontent.com/tjake/8995058fed11d9921e31/raw/a9334d1090017bf546d003e271747351a40692ea/blogpost.yaml -t 4

> (the last revision of the description had the wrong stack trace pasted and I've corrected that.)
> As you can see this 2nd assert on {{compaction-stress compact}} is triggered by SystemKeyspace class, so fix in StressProfile class is only able to solve the assert problem for {{compaction-stress write}}, but not {{compaction-stress compact}}.
