Reruns TestBulkLoadHFilesSplitRecovery using BulkLoadHFiles in secure mode. This suite is unable
to verify the security handoff/turnove as miniCluster is running as system user thus has root
privileges and delegation tokens don't seem to work on miniDFS.
<p/>
Thus SecureBulkload can only be completely verified by running integration tests against a secure
cluster. This suite is still invaluable as it verifies the other mechanisms that need to be
supported as part of a LoadIncrementalFiles call.
