I have checked the lib directories of hadoop and hive both, as the logs complains about the classpath, but the jar datanucleus-rdbms-3.2.9.jar is already in the folder. I have tried to restart the metastore service as well but it didnt help at all.
any other point which might cause the error above? i was curious if there were any config changes prior to the errors, but it seems like no config updates either...
EDIT
Verbose logs: http://pastebin.com/jggaXF1X

After digging the logs, as we were discussing with #NeilStockton in the comments, i have tried to redownload the related jar file, in the folder where the jar itself already exists... and it worked after the redownload...

Can't bind Hibernate session factory into java:app in WildFly 8.2.1

I am attempting to register a Hibernate Session Factory from a persistence unit in a applications deployed to WildFly 8.2.1 and I am encountering a warning exception from the Hibernate 4 code (listed below). And when I look at JNDI in the WildFly console, the session factories are definitely not registered. I would like them to be in the "java:app" scope so that I can avoid naming collisions when more that one application might have the same session factory name.
Registering an entity manager to this scope works fine.
If I leave the "java:app" prefix off the session factory name it bind just fine into JNDI, but at a global scope. I understand that I can impose some sort of name-spacing, but I was hoping I would not have to.
Any input would be appreciated. Thank you.
Details below...

I may have found the answer...
Although it is not exactly the answer I wanted. But, it makes sense. The reason that Hibernate's JNDI binding robots cannot find the java:app subcontext is because, I think, it is attempting to find that name at the root and it does not exist there. JBoss/WildFly on the other have seems to have some implicit context when deploying the application and actually as the java:app existing under the applications/<module-name> inside the JNDI tree. Hibernate doesn't know anything about this structure.
I've modified my implementation is organize these session factory bindings by application name at the root of the JNDI tree like this:
hib > myApp > sessions > MY_SESSION_FACTORY
I hope this helps someone else out.

Cannot apply class transformer without LoadTimeWeaver specified

Have a jar module with entities and daos (openjpa) and a web module which wires those up to controllers with spring. Tests in the jar module run fine but when trying to use daos in the web module, getting this error:

The problem is, I don't really understand the error. Google returns posts related to eclipse Link from 2007 which doesn't help much.
Any explanation of what my problem really is?

The problem is that OpenJPA tries to register a ClassTransformer with Spring and for whatever reason that isn't valid for this case. You don't mention what version of OpenJPA you're using, but I somewhat recall seeing a change that went in where OpenJPA will swallow this exception as it is benign if using build time enhancement.

Hibernate 4 ConnectionProvider Class not found

I just updated Hibernate in my application to 4.3.4 (from 3.X), which caused some problems. The first was the new method of creating a sessionFactory, which I resolved.
The next problem, which I'm finding nothing about, is that I am now getting a ClassNotFoundException on org.hibernate.connection.ConnectionProvider
It should be noted that I'm using BoneCP (0.7.1) for my connection pool, which was working before the upgrade.
Any help would be appreciated. I'm pretty new to hibernate (I'm working on implementing it as a POC), and I may have left out some important details from my description here as such.
I don't need it to be the newest version, so I can revert back, but it would be nice to have the latest and greatest :)
Thanks!

Hibernate keeps changing the package containing the ConnectionProvider base class. It changed from version 3 to 4 and has changed again with verson 4.3.
As #teresa-carrigan mentions in a comment to this answer, you'll have to compile the latest BoneCPConnectionProvider.java (currently supporting Hibernate 4.3.1) and use that.
Or use Hibernate version 4.2.12.Final and see if that works with BoneCP 0.8 (as explained in the aforementioned answer).

Where DistributionSamplerMappings.xml lives in the same dir as the application context.
I've tried using the spring-xml jar 1.2.1 and 1.5.3. but none of them seem to help.
The exception being thrown back is:

I'm using Spring 2.5.6 and Castor 1.3.1.
Looking around I find I'm not the only one who has had this problem, but I don't seem to be able to find a solution.
Any help would be much appreciated.

First, look at the code - line 118 of the XMLContextFactoryBean is the last one here. It suggests that somehow mappingResource is null. That suggests that getClass().getClassLoader().getResource(mappingLocation) is returning a null, so perhaps it can't find your file.
mappingLocation = (String) iter.next();
URL mappingResource = getClass().getClassLoader()
.getResource(mappingLocation);
mapping.loadMapping(new InputSource(mappingResource
.openStream())); // NPE occurs on this line.
Now if you want the class loader to find a file, you need to put the file in the same place that it would look for classes. Putting your DistributionSamplerMappings.xml in the same directory as applicationContext isn't good enough. Try WEB-INF/classes, or whichever is the classes folder that has the root of your compiled classes inside it. If you're using Eclipse, you can do this by putting the file inside your source folder -- it looks a bit untidy, since you'd rather have config info elsewhere, but at least it will work.

This exception can also occur if a mapped class doesn't have a default public constructor.
