You need to add the Hadoop and HBase libraries to the Hadoop Classpath. You successfully added it on the classpath of your mainproject but when it submits the job to Hadoop, the classpath is lost. The easiest way is to modify hadoop_env.sh. Another way would be to submit the jars for hbase and hadoop with your job submission Regards, Dhaval
