Hello :) When I run the SinglePageRankComputation example, using the following cmd line:
hadoop jar giraph-examples-1.1.0-SNAPSHOT-for-hadoop-2.0.3-alpha-jar-with-dependencies.jar org.apache.giraph.GiraphRunner org.apache.giraph.examples.SimplePageRankComputation -vif org.apache.giraph.io.formats.JsonLongDoubleFloatDoubleVertexInputFormat -vip /input/input.txt -of org.apache.giraph.io.formats.IdWithValueTextOutputFormat -op /outPageRank -w 1 -mc org.apache.giraph.examples.SimplePageRankComputation\$SimplePageRankMasterCompute I am getting the following error: "13/07/20 18:37:57 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable 13/07/20 18:37:58 INFO utils.ConfigurationUtils: No edge input format specified. Ensure your InputFormat does not require one. 13/07/20 18:37:58 INFO yarn.GiraphYarnClient: Final output path is: hdfs://localhost:9000/outPageRank 13/07/20 18:37:58 INFO service.AbstractService: Service:org.apache.hadoop.yarn.client.YarnClientImpl is inited. Exception in thread "main" java.lang.IllegalArgumentException: Giraph on YARN does not currentlysupport Giraph-managed ZK instances: use a standalone ZooKeeper: 'null' at org.apache.giraph.yarn.GiraphYarnClient.checkJobLocalZooKeeperSupported(GiraphYarnClient.java:392) at org.apache.giraph.yarn.GiraphYarnClient.run(GiraphYarnClient.java:106) at org.apache.giraph.GiraphRunner.run(GiraphRunner.java:96) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:70) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:84) at org.apache.giraph.GiraphRunner.main(GiraphRunner.java:126) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at org.apache.hadoop.util.RunJar.main(RunJar.java:212)" I couldn't fine anything about this Zookeeper error on google, any hints? Since the PageRankBenchmark is not working on Yarn, what are the examples actually working on the current versions? Oh, another thing: Does anyone knows how to remove the: "13/07/20 18:37:57 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable" On Hadoop Yarn 2.0.3-alpha? Best regards, Marco
