[SPARK-5352][GraphX] Add getPartitionStrategy in Graph Graph remembers an applied partition strategy in partitionBy() and returns it via getPartitionStrategy(). This is useful in case of the following situation; val g1 = GraphLoader.edgeListFile(sc, "graph.txt") val g2 = g1.partitionBy(EdgePartition2D, 2) // Modify (e.g., add, contract, ...) edges in g2 val newEdges = ... // Re-build a new graph based on g2 val g3 = Graph(g1.vertices, newEdges) // Partition edges in a similar way of g2 val g4 = g3.partitionBy(g2.getPartitionStrategy, 2) You can merge this pull request into a Git repository by running: $ git pull https://github.com/maropu/spark PartitionStrategyInGraph Alternatively you can review and apply these changes as the patch at: https://github.com/apache/spark/pull/5549.patch To close this pull request, make a commit to your master/trunk branch with (at least) the following in the commit message: This closes #5549 ---- commit 084ae5a80c96cb481c2b7d3f5aced99b09619057 Author: Takeshi YAMAMURO <linguin....@gmail.com> Date: 2015-04-17T04:05:13Z Add getPartitionStrategy commit c46d126a044d089f70b1c38b3cdb4979b6ffe589 Author: Takeshi YAMAMURO <linguin....@gmail.com> Date: 2015-04-17T04:54:38Z Add an new entry in MimaExlucdes.scala ---- --- If your project is set up for it, you can reply to this email and have your reply appear on GitHub as well.
