NullPointerException when trying to run sample or shell

[Joe Mihm]

Hi guys,

I am pretty new to hadoop and stumbled across Nectar and am having some trouble trying to run the sample and the shell.

> java -cp Nectar-analytics-0.0.1-SNAPSHOT.jar:covariance.jar  com.test.Covariance
Exception in thread "main" java.util.concurrent.ExecutionException: java.lang.NullPointerException

I have access to  a hadoop cluster via ssh that I have added and downloaded Nectar, set HADOOP_HOME, and created an input folder with book.csv.

Note: Nectar-analytics-0.0.1-SNAPSHOT.jar is not in HADOOP_HOME but in currently in the same folder as covariance.jar. I didn't think this would be a problem yet.

Thanks for any help.
