Summary: Fix makeSymmetricUnweighted
Key: GIRAPH-1052
URL: https://issues.apache.org/jira/browse/GIRAPH-1052
Project: Giraph
Issue Type: Bug
Reporter: Maja Kabiljo
Assignee: Maja Kabiljo
PrepareGraphPieces.makeSymmetricUnweighted is currently very inefficient for
skewed degree graphs, because it reuses set objects based on the number of in
edges, but also adds all out edges to the set, so sets which should be small
can become huge.
