For the feature completeness, we should guard out users who specify remote
jars with `--jars` in cluster mode, your use case of HBase is just one special
case, user could specify HBase dependencies with `--jars`, it is feasible. One
the contrary, you can also specify a local `primaryResource` as a workaround.
