0.4.9

Resolve an O(n!)-ish behavior in work claiming.
Previously, clusters with a large number of work units may have observed
high levels of ZooKeeper activity due to unnecessary claim cycles being
triggered. On launch, Ordasity's attempt to claim work results in
VerifyIntegrityListener being fired, which triggers an additional
recursive call to claimWork(). This cycle would continue until all work
units were claimed. In a local test of 2600 work units, this took over
an hour to complete and issued 3.5 million fruitless writes against ZK.
Sincere apologies for this bug, which may have been with us since the very
beginning.

0.4.3

Guard against a distributed race condition in which a node shuts down…
… a work unit immediately after receiving handoff without deleting the ZNode. Implemented by performing one final check of a ZNode's ownership before shutting it down. This check requires making a GET call to ZK and introduces IO in a method I'd prefer there be none, but it is the final condition checked and is quite rare.

0.4.2

Bump to 0.4.2: Add an extra safeguard on BalancingPolicy to avoid get…
…ting stuck in a claim loop if a listener fires multiple times, and only call startWork on listeners if we can guarantee that the work unit isn't already active by checking set membership.

0.4.0

Merge in changes for Ordasity 0.4.0.

0.2.0

Only continue waiting for a claim ZNode to become availalble if it's …
…not already held by me.

0.1.9

Resolve re-join issue resulting from a Zookeeper disconnect and recon…
…nect before session expiration. Migrate to JSON for node state info. Bump version to 0.1.9.
