[jira] [Commented] (CASSANDRA-16911) Remove ephemeral snapshot
marker file and introduce a flag to SnapshotManifest
[ https://issues.apache.org/jira/browse/CASSANDRA-16911?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17423910#comment-17423910 ]

-----------------------------------------------
I am stuck on not knowing how to write an upgrade test from 4.0 to 4.1 in jvm dtest, this case does not seem to be covered yet https://github.com/apache/cassandra/blob/trunk/test/distributed/org/apache/cassandra/distributed/upgrade/UpgradeTestBase.java#L82-L86

> While creating an ephemeral snapshot, a marker file is created at disk in a respective snapshot directory. This is not necessary anymore as we have introduced SnapshotManifest in CASSANDRA-16789 so we can move this flag there. By putting the information if a snapshot is ephemeral or not into SnapshotManifest, we simplify and "clean up" the snapshotting process and related codebase.
