so i tried keep getting an invocation exception when attempting to do k-means clustering and it is really crucial that i get around this problem...
i am checking out the code from the alternate repo svn co http://svn.apache.org/repos/asf/lucene/mahout/trunk here is my command hadoop jar /mahout/core/target/mahout-core-0.4-SNAPSHOT.job org.apache.mahout.clustering.kmeans.KMeansDriver -i trecdata-vectors/vectors/part-00000 -o trecdata-kmeans-clusters -c clusters -dm org.apache.mahout.common.distance.CosineDistanceMeasure -x 20 -cd 0.5 -k 26 -ow -r 8 -cl here is my output java.lang.RuntimeException: Error in configuring object at org.apache.hadoop.util.ReflectionUtils.setJobConf(ReflectionUtils.java:93) at org.apache.hadoop.util.ReflectionUtils.setConf(ReflectionUtils.java:64) at org.apache.hadoop.util.ReflectionUtils.newInstance(ReflectionUtils.java:117) at org.apache.hadoop.mapred.MapTask.runOldMapper(MapTask.java:354) at org.apache.hadoop.mapred.MapTask.run(MapTask.java:307) at org.apache.hadoop.mapred.Child.main(Child.java:170) Caused by: java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.hadoop.util.ReflectionUtils.setJobConf(ReflectionUtils.java:88) ... 5 more Caused by: java.lang.RuntimeException: Error in configuring object at org.apache.hadoop.util.ReflectionUtils.setJobConf(ReflectionUtils.java:93) at org.apache.hadoop.util.ReflectionUtils.setConf(ReflectionUtils.java:64) at org.apache.hadoop.util.ReflectionUtils.newInstance(ReflectionUtils.java:117) at org.apache.hadoop.mapred.MapRunner.configure(MapRunner.java:34) ... 10 more Caused by: java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.hadoop.util.ReflectionUtils.setJobConf(ReflectionUtils.java:88) ... 13 more Caused by: java.lang.IllegalStateException: Cluster is empty! at org.apache.mahout.clustering.kmeans.KMeansMapper.configure(KMeansMapper.java:74) ... 18 more ----- --cheers Delroy -- View this message in context: http://lucene.472066.n3.nabble.com/k-means-invocation-exception-still-not-resolved-tp835261p835261.html Sent from the Mahout User List mailing list archive at Nabble.com.
