Metacat

Reverting previous @Overrides chanrge from r6470, as that is the desired
behavior under Java 1.6 -- previous versions of Java (e.g., 1.5) will not
comile with this usage of the @Overrides annotation, but the currently
supported version will. So reverting to the 1.6 convention.

Removing incorrect @Override annotations that were preventing compilation. The methods marked did not actually override a method in the superclass, so they were not compiling. I think @Overrides was being mistaken for methods that implement an interface but aren't actually in the superclass.

Remove references to CNReplicationTask.

Remove the CNReplicationTask (for now). We will be using Metacat's ForceReplicationHandler to replicate science metadata across CNs, and may explore the use of a 100% evicted hzScienceMetadata map. Either way, the distributed task design won't be needed. When a dropped CN comes back online, we'll catch it up based on last modified dates for PIDs in the hzSystemMetadata map.

Add getNodesMap() to return the hzNodes map from the process cluster. Remove getPendingReplicationTasks since that structure is being removed. Add minor documentation.

lookup latest system metadata update date for use in synchronizing CN-CN when an offline nodes comes back online

changed the key type from Identifier to String for ObjectPathMap. (need a Comparable key).

rework this to be MN->MN replication. Should be fleshed out more.

throw RuntimeExceptions when store() methods throw declared exceptions -- we want callers to put() to be alerted if there are errors.

move CNReplicationTask to the hazelcast package
