Metacat

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 properties for strings used to connect to the DataONE storage and process Hazelcast clusters. The storage cluster is defined in the hazelcast.xml config file, and we list the names of the systemMetadataMap and the tasksIdNamespace in order to connect to these structures. When creating CNReplicationTask objects, use the task id generator to get a unique task id.

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 the hazelcast client jar so Metacat can connect to the DataONE storage cluster that initializes the hzNodes shared node map and other structures as needed.

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.

Update test for getReplicationStatus to reflect API change.

Newest version of the D1 0.6.4 common jar.

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'.

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.

Add the dataone.hazelcast.configFilePath property to be used when MetacatServlet becomes a Hazelcast cluster member using HazelcastService. TODO: what are the consequences of restarting the service via doRefresh()? It's set to false for now.
