Clustering error in Solr 8.2.0
Hi,
I am currently working on the upgrade from Solr 7.7.1 to Solr 8.2.0.
For the clustering, I am using lingo3g. There was no error in the earlier
version, but I am getting this error in Solr 8.2.0, even though the
configurations are the same.
This is my configuration for clustering in solrconfig.xml:
<searchComponent name="clustering"

Re: Clustering error in Solr 8.2.0
Posted by Zheng Lin Edwin Yeo <ed...@gmail.com>.
For lingo3g, they have replaced commons-lang with commons-lang3 in version
1.16, which should be in line with what Solr has done.
Just that our lingo3g licence does not allow us to upgrade to the new
version 1.16, and if we stick to the older version 1.15.1, it requires the
use of commons-lang.

Edwin

Depends if they do breaking changes in common-lang or not.
By using an old version of a library such as common-lang you may introduce security issues in your setup.

Re: Clustering error in Solr 8.2.0

I have found that the Lingo3GClusteringAlgorithm will work if I copied
the commons-lang-2.6.jar from the previous version to
solr-8.2.0\server\solr-webapp\webapp\WEB-INF\lib.
Will this work in the long run? Because our lingo3g licence is not eligible
to download the latest version of 1.16, so we are currently stuck with the
older version 1.15.1, which still uses commons-lang dependency.

Edwin

Hi Kevin,
Thanks for the info.
I think should be lingo3g problem. The problem occurs when I use
Lingo3GClusteringAlgorithm.
<str
name="carrot.algorithm">com.carrotsearch.lingo3g.Lingo3GClusteringAlgorithm</str>
If I change back to LingoClusteringAlgorithm, it will work.
<str
name="carrot.algorithm">org.carrot2.clustering.lingo.LingoClusteringAlgorithm</str>

According to the stack trace:
java.lang.NoClassDefFoundError: org/apache/commons/lang/ObjectUtils
at lingo3g.s.hashCode(Unknown Source)
It looks like lingo3g - lingo3g isn't on Maven central and looks like it
requires a license to download. You would have to contact them to see if it
still uses commons-lang. You could also copy in commons-lang dependency.

Hi Erick,
Thanks for your reply.
My clustering code is taken as it is from the Solr package, only the codes
related to lingo3g is taken from previous version.
Below are the 3 files that I have taken from previous version:
- lingo3g-1.15.0
- morfologik-fsa-2.1.1
- morfologik-stemming-2.1.1
Does anyone of these could have caused the error?

Edwin

This dependency was removed as part of https://issues.apache.org/jira/browse/SOLR-9079, so my guess is you’re pointing to an old version of the clustering code.
