[jira] [Comment Edited] (CASSANDRA-15552) Fix flaky test
org.apache.cassandra.db.repair.PendingAntiCompactionBytemanTest.testExceptionAnticompaction
[ https://issues.apache.org/jira/browse/CASSANDRA-15552?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17035564#comment-17035564 ]

I changed the test to print what's compacting when it fails, and most of the time it fails with 4 sstables compacting, in either cfs or cfs2. This at least makes some sense since both CFs contain 4 sstables. However, sometimes it fails with only two:
{code}
[junit-timeout] Testcase: testExceptionAnticompaction(org.apache.cassandra.db.repair.PendingAntiCompactionBytemanTest): FAILED
[junit-timeout] Nothing should be compacting: [BigTableReader(path='/home/debian/cassandra/build/test/cassandra/data:0/ks_1581462173137/tbl2-a21085804d2211ea92ecf9c4ecc0407d/na-3-big-Data.db'), BigTableReader(pa
th='/home/debian/cassandra/build/test/cassandra/data:0/ks_1581462173137/tbl2-a21085804d2211ea92ecf9c4ecc0407d/na-4-big-Data.db')]
{code}
I also move the getLiveSSTables assertions before the empty check, and those always pass.
