I was able to get a Java based client up using Hbase which seems to work just
fine, but when I stuck a JDO layer on top via DataNucleus, I got some weird
behavior during update. It seemed liked I could insert records, delete
records, and read records, but when I try to do an update, the record gets
removed!
Has anyone else had an issue like this? My testing code was pretty
primitive so I'm wondering if it might be a configuration issue with
hbase/zookeeper or something else:
public void test() {
File propsFile = new
File(AbstractPersistenceTest.DATA_NUCLEUS_PROPERTIES);
PersistenceManagerFactory pmf =
JDOHelper.getPersistenceManagerFactory(propsFile);
PersistenceManager pm = pmf.getPersistenceManager();
Transaction tx = pm.currentTransaction();
Fake entity = null;
try {
tx.begin();
entity = createEntity();
pm.makePersistent(entity);
tx.commit();
} finally {
if (tx.isActive()) {
tx.rollback();
}
}
String oldUUID = entity.getId();
String updatedName = "New Name";
tx = pm.currentTransaction();
try {
tx.begin();
Fake readEntity = null;
readEntity = (Fake)pm.getObjectById(entity.getClass(), entity.getId());
readEntity.setName(updatedName);
tx.commit();
} finally {
if (tx.isActive()) {
tx.rollback();
}
}
Fake updatedEntity = (Fake)pm.getObjectById(entity.getClass(), oldUUID);
// fails here. can't find record
assertEquals(updatedName, updatedEntity.getName());
}
