I have encountered a problem to using OffHeapVerticesInfo to load vertex in RAM. I set the configuration of the job in this way : Conf.setClass("hama.graph.vertices.info",org.apache.hama.graph.OffHeapVerticesInfo.class,org.apache.hama.graph.VerticesInfo.class); and the version of hama I used is latest hama-0.6.4., and the algorithm is just a simple PageRank. Then I get the error: I tried to solve this bug with add Apache DirectMemory libraries to lib folder but it doesn't work. I choose two jar from maven dependencies: directmemory-cache-0.2.jar directmemory-kryo-0.2.jar to add in hama's lib folder. The error information is as same as last time. I want know is there anyone meet the same question as me, and how to solve it. Thanks a lot. ------------------ Manna Xu Cluster and Grid Computing Lab School of Computer Science and Technology Huazhong University of Science and Technology Wuhan, 430074, China
