Another interesting sidenote, from my explorations with trying to see
what's up with the YARN tests: if you have an unclean working
directory, and your tests or instance attempts recovery, it will fail
miserably because of the package change. A look in the log reveals
why:


>INFO: The root directory of the local resource repository is 
>/tmp/storage/storage
>org.apache.hyracks.api.exceptions.HyracksDataException: 
>java.lang.ClassNotFoundException: 
>>edu.uci.ics.hyracks.storage.common.file.LocalResource
>at 
>>org.apache.asterix.transaction.management.resource.PersistentLocalResourceRepository.readLocalResource(PersistentLocalResourceRepository.jav>a:304)
>at 
>org.apache.asterix.transaction.management.resource.PersistentLocalResourceRepository.initialize(PersistentLocalResourceRepository.java:168)
>at 
>org.apache.asterix.hyracks.bootstrap.NCApplicationEntryPoint.start(NCApplicationEntryPoint.java:114)
>at 
>org.apache.hyracks.control.nc.NodeControllerService.startApplication(NodeControllerService.java:318)
>at 
>org.apache.hyracks.control.nc.NodeControllerService.start(NodeControllerService.java:255)
>at org.apache.hyracks.control.nc.NCDriver.main(NCDriver.java:44)


Something we might want to keep in mind if we ever plan to change the
class path again :)
