CF 2021 Solr Error

[Christian-CF]

Hello,

we can't add collections in CF 2021 Update 2. It was working until we made the update. Now we reveice this message: 

org.apache.solr.client.solrj.impl.HttpSolrClient$RemoteSolrException

Any ideas what the problem could be?

Is there any documentation what should be configured in Solr? I thought that this service is out-of-the-box and no need to configure anything.

[deleted message]

It was sent by mistake before being completed. 

[Charlie Arehart]

Yep, it IS indeed ready "out of the box". And FWIW, I can create a new collection in the CF Admin in CF2021 with update 2. So whatever is amiss, it seems something on your end there.

And any of many issues could be amiss, which may have nothing to do with the update, really. So please tell us:

• Are you running a cfcollection tag to creat this collection? or using the CF admin?
• Is the "coldfusion 2021 add-on" service installed and running? If you're on Windows, you'd see it in Windows Services, next to the CF service. If it's not there, the person who installed CF did not choose to include it. It can be added after the fact, using an installer at the CF downloads page.
• if you see it running, then in the cf admin "solr server" page, you will see the domain and port CF thinks it should use to talk to the solr service. visit that url in your browser, as in http://localhost:8993/ If that service is running, you will see the browser show two links, one of which is for solr. If it's working, when you click it you will see a nice solr admin (that many don't realize is there). If you see errors, then there was a problem with the solr (add-on) service. There are logs for it in the (by default) ColdFusion2021\cfusion\jetty\logs folder
• If you go to the "coldfusiuon collections" page in the CF Admin, what do you see? Any error? Can you create a new collection there?
• When things were working BEFORE, was it that you were running this all ok on cf2021 update 1? or CF2021 with no updates? Or might this be your first attempt to run this app on CF2021 (And it just happens to have been installed and updated to update 2 already for you?)

Just trying to help narrow down where things are failing for you. Hope that's helpful.

Hi Charlie,

I'm very thankful for your help! I will try to answer the questions:

- Normally I use the cfcollection tag, but the error is the same when using cfcollection or creating an collection in CF Admin

- We run Linux and the service is started

- When I go to "coldfusion collections" page there is no error. but when I enter an name and press "Create collection" I get:

"Unable to create collection test.
Unable to create Solr collection test.
An error occurred while creating the collection: org.apache.solr.client.solrj.impl.HttpSolrClient$RemoteSolrException. Check the Solr logs for more detail."

And the logs show the error above. 

- It was working on CF2021 with updater 1, that's we I thought there could be an connection.

I'm resurrecting this quasi-old thread because I'm having the same issue.

@Char - I downloaded the installer and run the installation (installing solr) only. When I logged back into CF admin and navigate to the ColdFusion Collection, I get the following error:

Unable to retrieve collections from the Search Services.
Ensure that you have installed ColdFusion Search Service and it is running.

Tried navigating to http://localhost:8993 - page can't be reached. I looked in Windows Services for the Solr service and I don't see it. 

Logs: ColdFusion2021\cfusion\jetty\logs do not exist. 

[--jojo--]

As a followup, I'm assuming that in Windows Services, "ColdFusion2021Add-onServices", runs solr?

[--jojo--]

Follow up to the follow up 🙂 

I re-installed it again, selecting everything on the list and this time, it fired up. Navigating to localhost:8993, shows the solr is started.

I can navigate to the ColdFusion Collection with no issues. With that said, when I try to create a new collection, I get the following error:

Unable to create collection faqs.
Unable to create Solr collection faqs.
An error occurred while creating the collection: org.apache.solr.client.solrj.impl.HttpSolrClient$RemoteSolrException. Check the Solr logs for more detail.

The logs show the following error:
112045 [qtp1794717576-16] ERROR org.apache.solr.handler.RequestHandlerBase - org.apache.solr.common.SolrException: Error CREATEing SolrCore 'faqs': Unable to create core [faqs] Caused by: Can't find resource 'solrconfig.xml' in classpath or 'C:\ColdFusion2021\cfusion\bin\ColdFusionSolr\multicore\collections\faqs'

And yes, I verified that the solrconfig.xml isn't there. It doesn't say anything about permissions, but could it be?
