Hi Adarsh,
I think your mapred.cache.files property has an extra space at the end. Try
removing that and let us know how it goes.
Thanks and Regards,

Thanks a Lot Sonal but it doesn't succeed.
Please if possible tell me the proper steps that are need to be followed
after Configuring Hadoop Cluster.
I don't believe that a simple commands succeeded as

You will probably have to use distcache to distribute your jar to all
the nodes too. Read the distcache documentation; Then on each node you
can add the new jar to the java.library.path through
mapred.child.java.opts.
You need to do something like the following in mapred-site.xml, where
fs-uri is the URI of the file system (something like
host.mycompany.com:54310).
<property>
<name>mapred.cache.files</name>
<value>hdfs://fs-uri/jcuda/jcuda.jar#jcuda.jar </value>
</property>
<property>
<name>mapred.create.symlink</name>
<value>yes</value>
</property>
<property>
<name>mapred.child.java.opts</name>
<value>-Djava.library.path=jcuda.jar</value>
</property>

Subject: Setting java.library.path for map-reduce job
Dear all,
I want to set some extra jars in java.library.path , used while running
map-reduce program in Hadoop Cluster.
I got a exception entitled "no jcuda in java.library.path" in each map
task.
I run my map-reduce code by below commands :
javac -classpath
/home/hadoop/project/hadoop-0.20.2/hadoop-0.20.2-core.jar://home/hadoop/
project/hadoop-0.20.2/jcuda_1.1_linux64/jcuda.jar:/home/hadoop/project/h
adoop-0.20.2/lib/commons-cli-1.2.jar
-d wordcount_classes1/ WordCount.java
jar -cvf wordcount1.jar -C wordcount_classes1/ .
bin/hadoop jar wordcount1.jar org.myorg.WordCount /user/hadoop/gutenberg
/user/hadoop/output1
Please guide how to achieve this.
Thanks & best Regards,
Adarsh Sharma
