> Ambari sends notifications in wrong order. ideally first generated Alert should be notified
first.
> This issue is reproducible in straight steps. 
> 1. Have 4 to 5 alerts generated in short span of time.
> 2. when Ambari notifier thread queries Database with the query like "select * from alert_notice
where notify_state = 'PENDING'" 
> This query returns last one first.
> Ex: 
> 2066	51	4876	PENDING	a11bffc9-3eda-42a7-b8ef-3f197cddfa26
> 2065	51	4874	PENDING	05e810cd-61a0-4d5c-9687-334aa71e0aaa
> 2064	51	4875	PENDING	b30999d3-0c78-46a3-aca4-f035743030b8
> 2063	51	4873	PENDING	9508afee-48dd-4599-a901-8d64ee07b909
> 2062	51	4872	PENDING	73d02181-138a-440e-8e8e-32f7ac5fbe2e
> 2061	51	4871	PENDING	42a134f0-f979-4be3-a51d-a5f804a11c89
> So Notified threads loops that list and sends one by one.
> This needs to be fixed. either have to read " order by notification_id" so that it gives
correct order.
