Large-memory improvements (Memory reduced vertex implementation, fast failure,
added settings)
-----------------------------------------------------------------------------------------------
Key: GIRAPH-91
URL: https://issues.apache.org/jira/browse/GIRAPH-91
Project: Giraph
Issue Type: Improvement
Reporter: Avery Ching
Current vertex implementation uses a HashMap for storing the edges, which is
quite memory heavy for large graphs. The default settings in Giraph need to be
improved for large graphs and heaps of >20G.
