let's assume there are 2 nodes, n1, n2. n1 is the coordinator.
1) n1 emits split
2) n1 and n2 complete split work
3) n1 becomes aware all replicas are ready for split
4) n2 restarts, but places split sstable into main group[1]
5) n1 executes split
6) n2 handles split completion, but see the main group is not empty
[1]: During split, main group should only contain unsplit sstables.
If all sstables are split, main must be empty.
This is a result of replica not setting storage group to split mode on restart
(using tablet map) and therefore sstables are incorrectly placed on main group.
The fix is about looking at tablet map and setting group to split mode before
sstables are populated into it.

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
