Hi, Giraph works with Gora 0.5 . So according to me, While packaging jdom is stored in a different location and is not a part of gora-hbase.jar. And when I upload the same jar file on the AWS EMR Cluster it is not able to locate its dependencies.

Your exception seems quite strange. `HBaseStore.readMapping()` is an always used method, and all tests pass. At the same time, I confirm you that gora-hbase has the dependency jdom [1] What version of Gora are you using? Let's see if we find something.
