 <div class="block">The user should override this method if they need a lock on an Entity. A lock can be anything,
  and it is up to the implementor. The Procedure Framework will call this method just before it
  invokes <a href="../../../../../../org/apache/hadoop/hbase/procedure2/Procedure.html#execute-TEnvironment-"><code>Procedure.execute(Object)</code></a>. It calls <a href="../../../../../../org/apache/hadoop/hbase/procedure2/Procedure.html#releaseLock-TEnvironment-"><code>Procedure.releaseLock(Object)</code></a> after the call to
  execute.
  <p/>
  If you need to hold the lock for the life of the Procedure -- i.e. you do not want any other
  Procedure interfering while this Procedure is running, see <a href="../../../../../../org/apache/hadoop/hbase/procedure2/Procedure.html#holdLock-TEnvironment-"><code>Procedure.holdLock(Object)</code></a>.
  <p/>
  Example: in our Master we can execute request in parallel for different tables. We can create
  t1 and create t2 and these creates can be executed at the same time. Anything else on t1/t2 is
  queued waiting that specific table create to happen.
  <p/>
  There are 3 LockState:
  <ul>
  <li>LOCK_ACQUIRED should be returned when the proc has the lock and the proc is ready to
  execute.</li>
  <li>LOCK_YIELD_WAIT should be returned when the proc has not the lock and the framework should
  take care of readding the procedure back to the runnable set for retry</li>
  <li>LOCK_EVENT_WAIT should be returned when the proc has not the lock and someone will take
  care of readding the procedure back to the runnable set when the lock is available.</li>

  with it, if they want to be abortable. The simplest implementation
  is to have an AtomicBoolean set in the abort() method and then the execute()
  will check if the abort flag is set or not.
  abort() may be called multiple times from the client, so the implementation
  must be idempotent.

  <p>NOTE: abort() is not like Thread.interrupt(). It is just a notification
  that allows the procedure implementor abort.</div>
