  1. Get rid of Integer reference comparison

    The current code does Integer reference comparisons. When possible
    int primitive type should be used.

    Addressed review feedback on rebalance scheduler

    jayjwylie authored
    - Changed default parallelism to "infinite" since scheduler throttles parallelism
    - Added TODOs for cleanup of scheduler
    - Added javadoc to document scheduler and its methods
    - Catch exceptions, log them, re-throw as VoldemmortRebalancingException
    A ton of white space changes due to futzing with eclipse code formatter preferences. Sorry.

    Tweak new rebalance scheduler

    jayjwylie authored
    Randomized the order of rebalance tasks in each stealer's list. This
    will avoid biasing the rebalance based on the order tasks were
  7. @jayjwylie

    Initial hack at new rebalance scheduler.

    jayjwylie authored
    Added RebalanceController.scheduler
    - limits each node to participating in a single task as either a stealer or donor.
    - randomizes the order in which tasks are attempted to be scheduled
    - not a clean implementation, but enough to evaluate.

    Tweaks to PartitionBalance and RebalancePlan

    jayjwylie authored
    - calculate partition-stores per zone.
    - This measure provides more context to evaluate the size of any plans to rebalance the cluster.
    - fix typo in verbose usage message

    Fix RebalanceUtils.getLatestCluster.

    jayjwylie authored
    - changed getLatestCluster to examine contents of cluster.xml on different nodes rather than timestamps since timestamps are incomparable across servers.
    - added a specific rebalance test that goes from current -> shuffle and then shuffle -> current. This confirms that rebalance can be invoked repeated times (if need be).
