Subject [jira] [Commented] (YARN-3045) [Event producers] Implement NM writing container lifecycle events to ATS
Date Sat, 01 Aug 2015 09:11:05 GMT

Naganarasimha G R commented on YARN-3045:
-----------------------------------------

[~sjlee0], Thanks for the detailed explanation now i am clear about the plans for TimelineClient
and indirect support of flush for it.
bq. If these events are already associated with containers any way, they are not an issue,
right?
Well [~djp] had pointed for 2 new stuff as part of this jira(apart from the existing container
life cycle events), one was NM side application events and other was container resource localization
events. In the later case again (similar to NM Side Application event) multiple resource paths
can be localized for a given container, so different states of localization cannot be directly
put as event ID's as we need to also publish the information of which resource this event
belongs too.   
hence had suggested earlier as :
??For Localization i feel it can be under ContainerEntity and the EventID can have Event Type
(REQUEST,LOCALIZED,LOCALIZATION_FAILED)and PATH of the localized resource.??
