Hello, Did anyone run John & Cailin Breadth-first search hadoop program? The original article is: http://www.johnandcailin.com/blog/cailin/breadth-first-graph-search-using-iterative-map-reduce-algorithm
I downloaded and played with it. It always issues the following errors. I am in single node environment. Hadoop version is 0.20.2 11/02/02 14:50:59 INFO mapred.JobClient: map 0% reduce 0% 11/02/02 14:51:08 INFO mapred.JobClient: Task Id : attempt_201102021048_0008_m_000000_0, Status : FAILED java.lang.ArrayIndexOutOfBoundsException: 1 at org.myorg.Node.(Node.java:26) at org.myorg.GraphSearch$MapClass.map(GraphSearch.java:69) at org.myorg.GraphSearch$MapClass.map(GraphSearch.java:61) at org.apache.hadoop.mapred.MapRunner.run(MapRunner.java:50) atorg.apache.hadoop.mapred.MapTask.runOldMapper(MapTask.java:358) at org.apache.hadoop.mapred.MapTask.run(MapTask.java:307) at org.apache.hadoop.mapred.Child.main(Child.java:170) Thank you
