Solr 8.1 issue with collection aliases

Jörn Franke
Hi,

I tried to upgrade from 8.0 to 8.1. I noticed that there is an issue with
collection aliases, but I am not 100% sure it is due to the upgrade.

Situation:
I have a collection called c_testcollection.
I have an alias called testcollection.
Alias "testcollection" points to "c_testcollection".
On Solr 8.0 no issue

After upgrade to Solr 8.1:
When I do a query on c_testcollection then there is no issue:
http://localhost:8983/solr/c_testcollection/select?q=test
When I do a query on testcollection then I receive the stacktrace below
http://localhost:8983/solr/testcollection/select?q=test

Additionally I observe a strange behavior in the admin ui. When I try to
create an alias (e.g. new) for a new collection (e.g. c_new) then it
creates two aliases:
new => c_new
c_new => c_new
if i then do a query on the alias new it works without issues. If I remove
the alias from c_new to c_new then I get the same error. Is this desired
behaviour?
It is rather annoying to have unnecessary aliases, because I need to filter
them out in my application when retrieving all aliases.
Is there a related issue.

Here the stacktrace:

Re: Solr 8.1 issue with collection aliases

Ishan Chattopadhyaya
Thanks Jörn for reporting this. Sounds like some backward comparability
break with aliases. Can you please open a JIRA? I'll take a look at
reproducing it soon.

In reply to this post by Jörn Franke
Note only an admin UI issue. Access collections via their alias does not work.

Re: Solr 8.1 issue with collection aliases

Jörn Franke
For the specific client the Solr 8.1 is not usable with this bug.

Collection aliases are also a crucial feature for doing “zero-downtime” reindexing or changing the Schema of a collection or for switching back to an old Index if the new Index structure has bugs etc.

However  I also understand that there are other considerations by other people.

Re: Solr 8.1 issue with collection aliases

Ishan Chattopadhyaya
Absolutely. This is a critical feature.
Andrzej, would you have time to do a 8.1.1 release? We also need to
coordinate with Jan, since he's doing a 7.7.2 release right now.
