[jira] [Commented] (CASSANDRA-13322) testall failure in
org.apache.cassandra.io.compress.CompressedRandomAccessReaderTest.testDataCorruptionDetection-compression
[ https://issues.apache.org/jira/browse/CASSANDRA-13322?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15934727#comment-15934727 ]
Alex Petrov commented on CASSANDRA-13322:
-----------------------------------------
Unfortunately, since this is a randomised test, we may possibly end up with non-corrupted data. We can do retries, but then we'll only decrease probability, it still may happen that we will write data that won't corrupt the sstable every once in a while.
What we should do, however, is making a {{Random}} there based on a seed and print seed in test results, to make it reproducible.
