Arvind Kandpal commented on CASSANDRA-21150:
--------------------------------------------
Update: I verified the fix locally using {*}_./.build/run-tests.sh -t
VerifyTest -a test-compression_{*}, and the build passed successfully.
I definitely learned a lot from this ticket—especially regarding how
{{build.xml}} configurations differ from manual local runs. I will make sure to
use the CI scripts for reproduction in the future to avoid such false positives.
I have updated the PR to apply the fix suggested by Sam (gating the data-file
read) and reverted the LZ4 changes.
Thanks [~samueldlightfoot] and [~dnk] for the guidance on this one!
