Kevin Risden updated SOLR-10087:
--------------------------------
Description:
StreamHandler currently can't uses jars that via the runtimeLib and Blob Store
api. This is because the StreamHandler uses core.getResourceLoader() instead of
core.getMemClassLoader() for loading classes.
An example of this working with the fix is here:
https://github.com/risdenk/solr_custom_streaming_expressions
Steps:
{code}
./bin/solr start -c -f -a "-Denable.runtime.lib=true"
# Create test collection
./bin/solr create -c test
# Create .system collection
curl 'http://localhost:8983/solr/admin/collections?action=CREATE&name=.system'
# build custom streaming expression
(cd custom-streaming-expression && mvn clean package)
# Upload jar to .system collection using Blob Store API
(https://cwiki.apache.org/confluence/display/solr/Blob+Store+API)
curl -X POST -H 'Content-Type: application/octet-stream' --data-binary
@custom-streaming-expression/target/custom-streaming-expression-1.0-SNAPSHOT.jar
'http://localhost:8983/solr/.system/blob/test'
# List all blobs that are stored
curl 'http://localhost:8983/solr/.system/blob?omitHeader=true'
# Add the jar to the runtime lib
curl 'http://localhost:8983/solr/test/config' -H
'Content-type:application/json' -d '{
"add-runtimelib": { "name":"test", "version":1 }
}'
# Create custom streaming expression using work from 9103
# Patch from SOLR-10087 is required for StreamHandler to load the runtimeLib jar
curl 'http://localhost:8983/solr/test/config' -H
'Content-type:application/json' -d '{
"create-expressible": {
"name": "customstreamingexpression",
"class": "com.test.solr.CustomStreamingExpression",
"runtimeLib": true
}
}'
# Test the custom streaming expression
curl 'http://localhost:8983/solr/test/stream?expr=customstreamingexpression()'
{code}
