Aleksey Yeschenko commented on CASSANDRA-11163:
-----------------------------------------------
bq. Yes, I should have noticed that SSTableReaderTest was a new failure in
https://builds.apache.org/view/A-D/view/Cassandra/job/Cassandra-3.0-test-all/248/#showFailuresLink
Realistically, you shouldn't have. Looking at Circle should be sufficient
enough. I just assumed that it would break on Circle just like it broke in our
internal CI and Jenkins, and that was wrong. My apologies for the somewhat
passive-aggressive righteous tone.
If Circle is green, we should be free to commit, and we should be checking with
ASF Jenkins from time to time, but it should not be required for every commit.
