| <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> |
