Exception starting filter SolrRequestFilter

almoehi

Hi,
on starting my alfresco instance (Community - 5.2.0, re21f2be5-b22), I get the following errors in catalina.out:

SCHWERWIEGEND: Exception starting filter SolrRequestFilter

SCHWERWIEGEND: Context [/solr] startup failed due to previous errors

So far, I didn't notice any malfunction of solr. The search within share works, although the first run is a bit slow. Does anyone know what causes this error? Can it be ignored?

Thanks in advance for your help,

Alex

This is a known issue with SOLR 1 logging in 5.x after an upgrade of the slf4j library.

SOLR 1 is deprecated and only supported for upgrade in 5.2. You should be using SOLR 4 or search services.

It is most likely you have SOLR 1 installed but you are not using it.

Is this a new instalation?

Have you done any kind of customization or deployed any new addon or something like that?

Hi Douglas,

thank you for your reply.

It's a relatively fresh install of Community - 5.2.0 (re21f2be5-b22) with an Apache proxy. It's not customized except for a different favicon and a logo on the top-left. However, I installed some addons:

Ezuno AddOn (Desktop Client)
Site-Creators AddOn

It's a good hint to start there, thanks a lot. When there's time to, I'll disable them to see if one is the cause.

I see.

Those addons/changes should not cause you any problems.

One thing you can try is to reindex your repository.

almoehi

Did a reindex according to Performing a full reindex with Solr | Alfresco Documentation . Exception is still there. Curiously the log did not contain such messages mentioned in the help documentation ("Creating new index"). However, the files were re-created and search works, although still the first query after every Alfresco restart is extremely slow (waited quite a while before testing, so reindexing should already have been completed). All succeeding queries run at good speed.

I had a look at the solr monitoring console, but could not spot any obvious problems. Everything looks ok.

Andy,

thanks for your reply. You were right, the exception was indeed caused by solr1. It was gone after removing all solr1 components:

<alfhome>/tomcat/webapps/solr
<alfhome>/tomcat/conf/Catalina/localhost/solr.xml
<alfhome>/alf_data/solr
