+ Internally we maintain a state for each region. The region state
is persisted in META. The state of META
+ region is persisted in ZooKeeper. If a region is in transition, its
state could be shown in the Master web UI.
+ <listitem><para>SPLIT: Server completed split of a region,
notified master</para></listitem>
+ <listitem><para>SPLITTING_NEW: New regions to be created when a
server splits a region</para></listitem>
+ <listitem><para>MERGED: Server completed merge two regions,
notified master</para></listitem>
+ <listitem><para>MERGING_NEW: A new region to be created when a
server merges two regions</para></listitem>
+ A region can transition from one state to another. The following
graph shows all the allowed transitions.
+ In the graph, each node is a state. A node has a color based on the
state type for easy understanding.
+ <listitem><para>Peru: Offline state, a special state that can be
transient (after closed before opening),
+ terminal (regions of disabled tables), or initial (regions of
newly created tables)</para></listitem>
