Metacat

load the evicted SM back into the map on a "Refresh" so that listeners hear the update. (metacat-index, for example)

In migrating to Hazelcast 2.4.x, replace deprecated methods. Use Hazelcast.newHazelcastInstance() rather than Hazelcast.init(). For other deprecated static methods, use the HazelcastInstance equivalent calls.

To attempt to address performance and stability WRT Hazelcast communication, we're upgrading to the 2.x series of Hazelcast. remove the 1.9.x jar files, and add the 2.4.1-SNAPSHOT jars. Modify HazelcastService to handle the minor change in the ItemListener interface (now passes ItemEvent<Identifier> as an argument)....

add count for the total processed pids (from ISet iterator)

allow SM resynch to be executed any time, not just during start up.

change to debug log level when processing shared/local pids)

only lock the missing pid event if we know we have it locally to contribute.
https://redmine.dataone.org/issues/3117

Add locking to the itemAdded() method so ideally only one CN will respond to the request for a 'wanted' pid from the cluster. The lock is on a string, not the pid, and so won't conflict with system metadata locking. The string is based on the pid, with "missing-" as a prefix.

only publish to the missing pid "wanted list" when resynching system metadata. we were seeing redundant entry added/updated events when looking up the shared systemmetadata first.

print the missing pid count, not the total shared pid count so we know how many will be processed.
