Hi Suneel,I had tried that before and it was not helpful. Here is the same
issue with the revised command (you can see math is in javac classpath):
javac -d /apps/analytics/ -classpath
.:/apps/mahout/trunk/core/target/mahout-core-0.9-SNAPSHOT.jar:/users/p529444/software/hadoop-1.0.3/hadoop-core-1.0.3.jar:/apps/mahout/trunk/core/target/mahout-core-0.9-SNAPSHOT-job.jar:/apps/mahout/trunk/math/target/mahout-math-0.9-SNAPSHOT.jar
SimpleKMeansClustering.java
-bash-4.1$ jar -cf myanalytics.jar myanalytics/
-bash-4.1$ hadoop jar /apps/analytics/myanalytics.jar
myanalytics.SimpleKMeansClustering -libjars
/apps/mahout/trunk/core/target/mahout-core-0.9-SNAPSHOT.jar
/apps/mahout/trunk/math/target/mahout-math-0.9-SNAPSHOT.jarWarning:
$HADOOP_HOME is deprecated.
