further development of ObjectPathMapLoader.

new class for refreshing the hazelcast map with metacat. Initial commit.

Add stub methods in CNodeService that implement the Hazelcast EntryListener interface: entryAdded(), entryRemoved(), entryUpdated(), and entryEvicted(). Add a listener to the hzSystemMetadata map so the CNodeService can respond to those events and create appropriate CNReplicationTask objects for distributed execution across the CN cluster. Again, stubs only so far.

Minor cleanup - tabs to spaces.

Enable CNodeService to access 1) the hzNodes map defined in the DataONE process cluster by becoming a Hazelcast client (hzClient) to that cluster and 2) the hzSystemMetadata map defined in the DataONE storage cluster by becoming a member to that cluster (using direct Hazelcast calls). Added fields for maintaining the DataONE cluster properties.

Add in the Hazelcast Id generation namespace and an IdGenerator instance for task ids. Hazelcast will produce cluster-wide unique ids for the "task-ids" namespace, to be used when creating CNreplicationTask objects.

Add a CNReplicationTask class that will be submitted to the CN storage cluster when there are changes to the object store involving system metadata, science metadata, and resource maps. When a new entry is added to the hzSystemMetadata map, a new data, science metadata, or resource map was added to the VO, and all CN cluster members need to be updated with the object and it's system metadata. This task is executed on each CN to replicate the information. If the event is an update to an existing system metadata entry, it may only involve a change to system metadata, or may involve a change to science metadata as well. The task will return with the PID of the object replicated, be it a sysmeta, scimeta, or resource object. Locking of the PID will be handled by the task.

Catch D1nodeService up to the DataONE 0.6.4 schema where there is no ObjectFormat.isScienceMetadata() method, but rather ObjectFormat.getFormatType() where type is currently one of 'DATA, 'METADATA', or 'RESOURCE'.

6401 09/11/2011 12:12 PM Chris Jones

Modify HazelcastService to read configuration information from an on-disk file (not from a jar file). Added init() to start up the service (was calling doRefresh() before. We still need to decide if this is a refreshable service.
