--------------------------------------
Summary: 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: 8.4.1, 7.7.2, 6.6.6
Reporter: Thomas Corthals
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$SynonymManager"}'
\
http://localhost:8983/solr/techproducts/schema/analysis/synonyms/testmap
curl -X DELETE
http://localhost:8983/solr/techproducts/schema/analysis/synonyms/testmap
curl http://localhost:8983/solr/admin/cores?action=RELOAD\&core=techproducts
curl -X PUT -H 'Content-type:application/json' --data-binary \
'{"class":"org.apache.solr.rest.schema.analysis.ManagedWordSetResource"}' \
http://localhost:8983/solr/techproducts/schema/analysis/stopwords/testlist
curl -X DELETE
http://localhost:8983/solr/techproducts/schema/analysis/stopwords/testlist
curl -X PUT -H 'Content-type:application/json' --data-binary \
'{"class":"org.apache.solr.rest.schema.analysis.ManagedSynonymGraphFilterFactory$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
{code}
The same successes/errors occur when running each cycle against a different
core if the cores share the same configset.
