Class jar issue

Hi all,

I am running hadoop/mapreduce/hdfs in eclipse and am seeing this error:

10/04/16 13:49:56 INFO security.Groups: Group mapping
impl=org.apache.hadoop.security.ShellBasedUnixGroupsMapping;
cacheTimeout=300000
10/04/16 13:49:56 WARN mapreduce.JobSubmitter: Use GenericOptionsParser for

classes may not be found. See Job or Job#setJar(String).

0003
10/04/16 13:49:56 ERROR slive.SliveTest: Unable to run jobs due to error:
java.lang.InstantiationException

Has anyone encountered that with eclipse?
If so is there a recommended solution.
It seems like the other tests that I am running are able to locate the jar
file, just not a new test I have added.

Any ideas would be great.
Thanks,
Joshua Harlow
