Hi, I am running the PageRank benchmark under giraph-examples from giraph-1.0.0 release. I am using the following command to run the job (as mentioned here )
vikesh@madmax /lfs/madmax/0/vikesh/usr/local/giraph/giraph-examples/src/main/java/org/apache/giraph/examples $ $HADOOP_HOME/bin/hadoop jar $GIRAPH_HOME/giraph-core/target/giraph-1.0.0-for-hadoop-0.20.203.0-jar-with-dependencies.jar org.apache.giraph.benchmark.PageRankBenchmark -e 1 -s 3 -v -V 50000000 -w 30 However, the job gets stuck at map 9% and is eventually killed by the JobTracker on reaching the mapred.task.timeout (default 10 minutes). I tried increasing the timeout to a very large value, and the job went on for over 8 hours without completion. I also tried the ShortestPathsBenchmark, which also fails the same way. Any help is appreciated. ****** ---------------- *********** Machine details: Linux version 2.6.32-279.14.1.el6.x86_64 ([email protected]) (gcc version 4.4.6 20120305 (Red Hat 4.4.6-4) (GCC) ) #1 SMP Tue Nov 6 23:43:09 UTC 2012 Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 64 On-line CPU(s) list: 0-63 Thread(s) per core: 1 Core(s) per socket: 8 CPU socket(s): 8 NUMA node(s): 8 Vendor ID: GenuineIntel CPU family: 6 Model: 47 Stepping: 2 CPU MHz: 1064.000 BogoMIPS: 5333.20 Virtualization: VT-x L1d cache: 32K L1i cache: 32K L2 cache: 256K L3 cache: 24576K NUMA node0 CPU(s): 1-8 NUMA node1 CPU(s): 9-16 NUMA node2 CPU(s): 17-24 NUMA node3 CPU(s): 25-32 NUMA node4 CPU(s): 0,33-39 NUMA node5 CPU(s): 40-47 NUMA node6 CPU(s): 48-55 NUMA node7 CPU(s): 56-63 I am using a pseudo-distributed Hadoop cluster on a single machine with 64-cores. *****-------------******* Thanks, Vikesh Khanna, Masters, Computer Science (Class of 2015) Stanford University
