Spring Batch with HiveTasklet giving error

I am trying to execute the apachelog hive example with hiveTasklet.

The hiveTasklet is launched but it throws error :

I could figure out that its because of change in hadoop program jar. It should pick hive-exec but it is picking hive-service.

Executing: /home/impadmin/hadoop-1.0.1/bin/hadoop jar /home/impadmin/hadoopBook/spring-data-book-master/hadoop/batch-wordcount-hive/target/appassembler/repo/hive-service-0.8.1.jar org.apache.hadoop.hive.ql.exec.ExecDriver

Could someone please help me to set the correct HiveJar.

Thanks
