ServerCrashProcedure.
<p>
By default retain assignment is disabled which makes the failover faster and improve the
availability; useful for cloud scenario where region block locality is not important. Enable
this when RegionServers are deployed on same host where Datanode are running, this will improve
read performance due to local read.

and it is up to the implementor. The Procedure Framework will call this method just before it

It calls <a href="../../../../../../org/apache/hadoop/hbase/procedure2/Procedure.html#releaseLock-TEnvironment-"><code>Procedure.releaseLock(Object)</code></a> after the call to

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>.

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
