Hi
I've run into an issue with creating a Managed Stopwords list that has the
same name as a previously deleted list. Going through the same flow with
Managed Synonyms doesn't result in this unexpected behaviour. Am I missing
something or did I discover a bug in Solr?
On a newly started solr with the techproducts core:
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
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:
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
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).
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
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.
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$SynonymManager"}'
http://localhost:8983/solr/techproducts/schema/analysis/synonyms/testmap
curl -X DELETE
http://localhost:8983/solr/techproducts/schema/analysis/synonyms/testmap
curl http://localhost:8983/solr/admin/cores?action=RELOAD\&core=techproducts
curl -X PUT -H 'Content-type:application/json' --data-binary
'{"class":"org.apache.solr.rest.schema.analysis.ManagedWordSetResource"}'
http://localhost:8983/solr/techproducts/schema/analysis/stopwords/testlist
curl -X DELETE
http://localhost:8983/solr/techproducts/schema/analysis/stopwords/testlist
curl -X PUT -H 'Content-type:application/json' --data-binary
'{"class":"org.apache.solr.rest.schema.analysis.ManagedSynonymGraphFilterFactory$SynonymManager"}'
http://localhost:8983/solr/techproducts/schema/analysis/synonyms/testmap
curl -X DELETE
http://localhost:8983/solr/techproducts/schema/analysis/synonyms/testmap
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
The same successes/errors occur when running each cycle against a different
core if the cores share the same configset.
Any ideas on what might be going wrong?
