Aster and hadoop connectivity - forum topic by nancyjean

Hi,
I am trying to connect Aster and hcatalog of hortonworks using the command load_from_hcatalog.
But evrytime I try to fire this query, it throws an error saying the following:
ERROR: failed to access hcatalog table mytable: FAILED: Error in metadata: javax.jdo.JDOFatalUserException: Class org.datanucleus.jdo.JDOPersistenceManagerFactory was not found.

NestedThrowables:

java.lang.ClassNotFoundException: org.datanucleus.jdo.JDOPersistenceManagerFactory
 
can any one tell what the problem here is?
Thanks in advance.
