Brandon Williams commented on CASSANDRA-17084:
----------------------------------------------
Thanks for looking. I think the issue is that circle's current working
directory when running the tests isn't the cassandra directory (and in
retrospect that was probably a bad assumption to begin with) so the directories
it's looking for actually do not exist at the base level, hence the NPE. I
updated the dtest to create its [own temp
directory|https://github.com/driftx/cassandra-dtest/commit/2c28040113e95bb277050e35fe60b3da2fd8edfa]
and point to relative (nonexistent) paths within that, and that fails without
my patch, and [passes on
circle|https://app.circleci.com/pipelines/github/driftx/cassandra?branch=CASSANDRA-17084&filter=all]
with it.
