Thomas Corthals updated SOLR-14268:
-----------------------------------
Labels: ManagedStopwordFilterFactory REST Solr (was: )
> Re-creating deleted Managed Stopwords lists results in error
> ------------------------------------------------------------
>
> Key: SOLR-14268
> URL: https://issues.apache.org/jira/browse/SOLR-14268
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Components: Schema and Analysis
> Affects Versions: 6.6.6, 7.7.2, 8.4.1
> Reporter: Thomas Corthals
> Priority: Major
> Labels: ManagedStopwordFilterFactory, REST, Solr
>
> Creating a Managed Stopwords list that has the same name as a previously
> deleted list results in an error if the core has been reloaded after deleting
> the list. Going through the same flow with Managed Synonyms doesn't result in
> this unexpected behaviour.
> On a newly started solr with the techproducts core:
> {code:bash}
> curl -X PUT -H 'Content-type:application/json' --data-binary \
> '{"class":"org.apache.solr.rest.schema.analysis.ManagedWordSetResource"}' \
> http://localhost:8983/solr/techproducts/schema/analysis/stopwords/testlist
> curl -X DELETE
> http://localhost:8983/solr/techproducts/schema/analysis/stopwords/testlist
> curl http://localhost:8983/solr/admin/cores?action=RELOAD\&core=techproducts
> curl -X PUT -H 'Content-type:application/json' --data-binary \
> '{"class":"org.apache.solr.rest.schema.analysis.ManagedWordSetResource"}' \
> http://localhost:8983/solr/techproducts/schema/analysis/stopwords/testlist
> {code}
> The second PUT request results in a status 500 with error msg
> "java.util.LinkedHashMap cannot be cast to java.util.List".
> Similar requests for synonyms work fine, no matter how many times I repeat
> the CREATE/DELETE/RELOAD cycle:
> {code:bash}
> curl -X PUT -H 'Content-type:application/json' --data-binary \
> '{"class":"org.apache.solr.rest.schema.analysis.ManagedSynonymGraphFilterFactory$SynonymManager"}'
> \
> http://localhost:8983/solr/techproducts/schema/analysis/synonyms/testmap
> curl -X DELETE
> http://localhost:8983/solr/techproducts/schema/analysis/synonyms/testmap
> curl http://localhost:8983/solr/admin/cores?action=RELOAD\&core=techproducts
> curl -X PUT -H 'Content-type:application/json' --data-binary \
> '{"class":"org.apache.solr.rest.schema.analysis.ManagedSynonymGraphFilterFactory$SynonymManager"}'
> \
> http://localhost:8983/solr/techproducts/schema/analysis/synonyms/testmap
> {code}
> Reloading after creating the Stopwords list but not after deleting it works
> without error too on a fresh techproducts core (you'll have to remove the
> directory from disk and create the core again after running the previous
> commands).
> {code:bash}
> curl -X PUT -H 'Content-type:application/json' --data-binary \
> '{"class":"org.apache.solr.rest.schema.analysis.ManagedWordSetResource"}' \
> http://localhost:8983/solr/techproducts/schema/analysis/stopwords/testlist
> curl http://localhost:8983/solr/admin/cores?action=RELOAD\&core=techproducts
> curl -X DELETE
> http://localhost:8983/solr/techproducts/schema/analysis/stopwords/testlist
> curl -X PUT -H 'Content-type:application/json' --data-binary \
> '{"class":"org.apache.solr.rest.schema.analysis.ManagedWordSetResource"}' \
> http://localhost:8983/solr/techproducts/schema/analysis/stopwords/testlist
> {code}
> And even curiouser, when doing a CREATE/DELETE for Stopwords, then a
> CREATE/DELETE for Synonyms, and only then a RELOAD of the core, the cycle can
> be completed twice. (Again, on a freshly created techproducts core.) Only the
> third attempt to create a list results in an error. Synonyms can still be
> created and deleted repeatedly after this.
> {code:bash}
> curl -X PUT -H 'Content-type:application/json' --data-binary \
> '{"class":"org.apache.solr.rest.schema.analysis.ManagedWordSetResource"}' \
> http://localhost:8983/solr/techproducts/schema/analysis/stopwords/testlist
> curl -X DELETE
> http://localhost:8983/solr/techproducts/schema/analysis/stopwords/testlist
> curl -X PUT -H 'Content-type:application/json' --data-binary \
> '{"class":"org.apache.solr.rest.schema.analysis.ManagedSynonymGraphFilterFactory$SynonymManager"}'

> http://localhost:8983/solr/techproducts/schema/analysis/synonyms/testmap
> curl -X DELETE
> http://localhost:8983/solr/techproducts/schema/analysis/synonyms/testmap

> {code}
> The same successes/errors occur when running each cycle against a different
> core if the cores share the same configset.
