eu.stratosphere.nephele.managementgraph.ManagementGraph
A management graph is structurally equal to the graph Nephele uses internally for scheduling jobs. Management graphs are intended to provide more fine-grained information about a job at runtime than available through the regular client interface, however, without exposing Nephele's internal scheduling data structures.
This class is not thread-safe.
