Review Comment:
I'll suggested to use `if (snapshotInfo.isSstFiltered() ||
snapshotInfo.getSnapshotStatus() !=
SnapshotInfo.SnapshotStatus.SNAPSHOT_DELETED)` at line number 186 instead of
loading DELETED snapshot. There is no point in cleaning deleted snapshot.
And add a catch at line 209 to double check that it fails only if snapshot
has been deleted.
```
} catch (OMException omException) {
if (snapshotInfo.getSnapshotStatus() ==
SnapshotInfo.SnapshotStatus.SNAPSHOT_DELETED) {
LOG.info("Snapshot with name: '{}', id: '{}' has been
deleted.",
snapshotInfo.getName(), snapshotInfo.getSnapshotId());
}
}
```
