Hello,
I intend to start a mapreduce job from another java app, using
ToolRunner.run method. This works fine on a local job. However when
distributed i get java.lang.NoClassDefFoundError:
org/rosuda/REngine/Rserve/RserveException
at java.lang.Class.getDeclaredConstructors0(Native Method)
at java.lang.Class.privateGetDeclaredConstructors(Class.java:2389)
at java.lang.Class.getConstructor0(Class.java:2699)
at java.lang.Class.getDeclaredConstructor(Class.java:1985)
at
org.apache.hadoop.util.ReflectionUtils.newInstance(ReflectionUtils.java:74)
at org.apache.hadoop.mapred.JobConf.getInputFormat(JobConf.java:402)
at org.apache.hadoop.mapred.MapTask.run(MapTask.java:219)
at
org.apache.hadoop.mapred.TaskTracker$Child.main(TaskTracker.java:2207)
Now, i have a CLASSPATH entry in my .bashrc which contains the
location of Rserve.jar (which contains the above classes), yet I still
get the above error.
Do I have to somehow emulate RunJar.main or is there a simpler way out?
Thank you
Saptarshi
