Subject [jira] [Commented] (CASSANDRA-11811) dtest failure in snapshot_test.TestArchiveCommitlog.test_archive_commitlog
Date Tue, 26 Jul 2016 11:27:21 GMT


Branimir Lambov commented on CASSANDRA-11811:

My understanding of the problem is that the second time the cluster was spawned it somehow
got a different configuration. Not surprisingly, restoring the snapshot then failed.

There doesn't seem to be anything wrong with the test, though, it does set the number of vnodes
properly in both cluster creation calls. I don't know how to treat this other than to say
that it is some random failure (something temporarily broke in the infrastructure?), especially
since for all the known history of this test it failed only on this specific run.
