Just putting this up to show people.  It's not done but the balanceCluster() method "works"
and has a bunch of test cases.

This addresses bug HBASE-2697.


  branches/0.90_master_rewrite/src/main/java/org/apache/hadoop/hbase/HServerInfo.java 961064


Diff: http://review.hbase.org/r/282/diff


Added TestLoadBalancer.testLoadBalancer_balanceCluster().  If you have any good edge cases
let me know!

>             Project: HBase
>          Issue Type: Sub-task
>          Components: ipc, master, regionserver
>            Reporter: Jonathan Gray

>            Priority: Critical
>             Fix For: 0.21.0
> This issue is doing the meat of what HBASE-2485 is about and continues what was started
in HBASE-2694 after some code cleanup to make life easier.
> This deals with no longer piggybacking messages from Master to RegionServers on heartbeat
responses and instead sending direct unsolicited messages.  This also deals with moving the
open/close logic fully into handlers and removing the existing open/close code on both the
RS and M sides.  There may also be some changes to the master in-memory state of regions in
transition.  The new load balancer will probably be introduced with this issue but not fully
integrated yet.
