Andrzej Bialecki commented on SOLR-13566:
------------------------------------------
{quote}But I was wondering if there should instead be a cached or fixed thread
pool for all DaemonStreams to limit the number of concurrent DaemonStreams? Or
are they limited elsewhere? Or are they intentionally unlimited?
{quote}
That's an excellent question. IMHO they should be limited (because everything
has its limits) but looking at the existing API it's not clear where the pool
should be created and injected (CoreContainer? SolrCore? StreamFactory?) and
what the default limits should be.
Since this specific issue is about a bug and not an optimization let's fix this
bug first and address the limits in another issue.

> f26388d034fe5eadca7416aa63b509b8db2c7688 so I have the authentication fixes
> from SOLR-13510 (intermittent 401s for internode requests)
>
> When trying to use the new REINDEXCOLLECTION command introduced in
> SOLR-11127 with basic auth enabled, the daemon stream fails with repeated
> 401s when trying to access the target collection.
>
> This might be the same problem as SOLR-13472, except it applies even with a
> single node, and this doesn't require role based configuration.
>
> Repro: I added a reindex request in BasicAuthIntegrationTest and it is
> reproducible in there... I don't know what effect it should have on the auth
> metrics, if it were working correctly, so I don't know how to update the test
> properly. But you can add the request towards the end of
> org.apache.solr.security.BasicAuthIntegrationTest.testBasicAuth()
>
> _CollectionAdminRequest.ReindexCollection reindexReq =
> CollectionAdminRequest.reindexCollection(COLLECTION);_
> _reindexReq.setBasicAuthCredentials("harry", "HarryIsUberCool");_
> _cluster.getSolrClient().request(reindexReq, COLLECTION);_
>
> Manual Repro:
> run bin/solr -e cloud
> Choose 1 node / 1 shard / 1 replica
> In browser GET
> [http://localhost:8983/solr/admin/collections?action=REINDEXCOLLECTION&name=gettingstarted]
> will succeed
> Enable security: server\scripts\cloud-scripts\zkcli -zkhost localhost:9983
> -cmd putfile /security.json <path to file with this>
>
> {

> In browser authenticate (as solradmin : solradmin) and GET
> [http://localhost:8983/solr/admin/collections?action=REINDEXCOLLECTION&name=gettingstarted]
> will time out after 180 seconds
>
> The solr log will show repeated 401s
>
> Setting "forwardCredentials" : true in the security.json does not appear to
> change the outcome.
>
>
> The daemon stream should probably be using PKI auth for the internal request.
