Review Comment:
@bvaradar @danny0405 there seems to be some discrepancy the 2 rollback
strategies below:
1. rollback with marker - will NOT delete log files that were created by the
commit to rollback
2. rollback via listing - will delete log files that were created by the
commit to rollback
``` java
// Log file can be deleted if the commit to rollback is also the commit
that created the fileGroup
if (latestLogFileOption.isPresent() && Objects.equals(baseCommitTime,
instantToRollback.getTimestamp())) {
Path fullDeletePath = new Path(partitionPath,
latestLogFileOption.get().getFileName());
return new HoodieRollbackRequest(relativePartitionPath, EMPTY_STRING,
EMPTY_STRING,
Collections.singletonList(fullDeletePath.toString()),
Collections.emptyMap());
}
```
Perhaps, a fix like this would be sufficient to resolve the discrepancy
between how these 2 strategies rollback log files?
