Varun Saxena commented on YARN-4224:
------------------------------------
So I looked at [~leftnoteasy]'s code at YARN-3368. I see that for single record
like a single app attempt, we are extending urlForFindRecord and that takes
only a single string id as input instead of an object as is the case with
urlForQuery. In case of app attempt and containers, we can get both appid from
app attempt id, and app attempt from container so a single id would do.
In our case no such relationship exists between cluster, user, flow, etc. Is
this why we need UID ? And we want to fetch it from server side so that UID
encoding can be easily changed in future ? Is my understanding correct ?
By the way what are implications of calling query instead of findRecord ? I
guess multiple fields can be passed when we call urlForQuery.
Moreover, what do you mean by batch query ? Does that mean support for multiple
optional query parameters like filters etc. to trim down the results ? We
already have them.
