I installed Hama 0.5 on 4 racks (4 x 18 nodes) w/ 3 tasks per each node (bsp.child.java.opts = Xmx3512m), tried to run PageRank on Wikipedia dataset introduced at http://wiki.apache.org/hama/WriteHamaGraphFile
Doesn't work, the cause of job fail error is different every time. NullPointerException at loadVertices(), ERROR bsp.BSPTask: Started pinging to groom, ..., etc. Has anyone tried this? -- Best Regards, Edward J. Yoon @eddieyoon
