Task #3116: Metacat CN startup and initialization time needs to be reduced an order of magnitude
Reduce Hazelcast.init() startup time for populating hzSystemMetadata
100%
Description
Metacat's HazelcastService needs to be modified to add an ItemListener on hzMissingIdentifiers (or potentially do this in a sibling listener class called by HazelcastService. This may be done in the resynchToRemote() method and in a thread. The listener will call ILock.tryLock('missing-{pid}') in order to keep the lock namespace separate from the actual pid lock, but all three CNs will participate in this lock to reduce repeated calls to put() on the system metadata map.

This is incorporated into the Metacat 2.0.3 release (currently being tested as RCx).
Tests in the sandbox (1/3 and 2/3 servers with missing entries) and stage (2K entries missing on a single server) environments have been successful.
