Lock the system metadata entry in hzSystemMetadata when calling setReplicationPolicy().
Lock the system metadata entry in hzSystemMetadata when calling registerSystemMetadata().
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.
Change isNodeAuthorized() to query the hzSystemMetadata map rather than the hzPendingreplicationTasks map. The latter isn't needed for authorization since the ReplicationStatus for each Replica in SystemMetadata lists the status of the replica and can be queried.
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.
