@InterfaceAudience.Public @InterfaceStability.Stable public abstract Map<String,ByteBuffer> getAllServicesMetaData()
Get the meta-data from all auxiliary services running on the
NodeManager
.
The meta-data is returned as a Map between the auxiliary service names and
their corresponding per service meta-data as an opaque blob
ByteBuffer
To be able to interpret the per-service meta-data, you should consult the documentation for the Auxiliary-service configured on the NodeManager
