> When ACL is enabled and Kerberos is not enabled, the snapshot owner cannot delete the snapshot. This is because the owner of the snapshot cannot be taken during permission verification. By investigation, found that only after HBase has enabled security authentication, the owner will be set when doing snapshot.
