Gus Heck commented on SOLR-12258:
---------------------------------
Yeah I like that. I wasn't a fan of the secondTry arg either, except I'm not
sure if we can put the aliasManager.update() in the same try bloack as
.forceUpdateCollection() since we probably still want to force update the
collection even if aliases update isn't happy... either that or we don't want
to ignore the exception after all.
> V2 API should "retry" for unresolved collections/aliases (like V1 does)

> When using V1, if the request refers to a possible collection/alias that
> fails to resolve, HttpSolrCall will invoke AliasesManager.update() then retry
> the request as if anew (in collaboration with SolrDispatchFilter). If it
> fails to resolve again we stop there and return an error; it doesn't go on
> forever.
> V2 (V2HttpCall specifically) doesn't have this retry mechanism. It'll return
> "no such collection or alias".
> The retry will not only work for an alias but the retrying is a delay that
> will at least help the odds of a newly made collection from being known to
> this Solr node. It'd be nice if this was more explicit – i.e. if there was a
> mechanism similar to AliasesManager.update() but for a collection. I'm not
> sure how to do that?
> BTW I discovered this while debugging a Jenkins failure of
> TimeRoutedAliasUpdateProcessorTest.test where it early on simply goes to
> issue a V2 based request to change the configuration of a collection that was
> created immediately before it. It's pretty mysterious. I am aware of
> SolrCloudTestCase.waitForState which is maybe something that needs to be
> called? But if that were true then *every* SolrCloud test would need to use
> it; it just seems wrong to me that we ought to use this method commonly.
