Subject [jira] [Commented] (YARN-5585) [Atsv2] Add a new filter fromId in REST endpoints
Date Thu, 01 Sep 2016 12:00:26 GMT

    [ https://issues.apache.org/jira/browse/YARN-5585?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15455180#comment-15455180
] 

Varun Saxena commented on YARN-5585:
------------------------------------

bq. But I am not sure that does HBase filters can support to scan the rows which are less
than or greater than id's.
As I indicated in my comment above, this can be easily done in HBase by setting start row
in HBase Scan. Limit (use Page Filter for it) will anyways limit the number of entities returned.

However this would work well only for apps within a flow run and wont work well with apps
within a flow as 2 flow runs may be executing simultaneously.

> TimelineReader REST API's provides lot of filters to retrieve the applications. Along
with those, it would be good to add new filter i.e fromId so that entities can be retrieved
after the fromId. 
> Example : If applications are stored database, app-1 app-2 ... app-10.
> *getApps?limit=5* gives app-1 to app-10. But to retrieve next 5 apps, it is difficult.
> So proposal is to have fromId in the filter like *getApps?limit=5&&fromId=app-5*
which gives list of apps from app-6 to app-10. 
> This is very useful for pagination in web UI.
