Sudheer Prem created SOLR-4561:
----------------------------------
Summary: CachedSqlEntityProcessor with parametarized query is
broken
Key: SOLR-4561
URL: https://issues.apache.org/jira/browse/SOLR-4561
Project: Solr
Issue Type: Bug
Components: contrib - DataImportHandler
Affects Versions: 4.1
Reporter: Sudheer Prem
When child entities are created and the child entity is provided with a
parametrized query as below,
<entity name="x" query="select * from x">
<entity name="y" query="select * from y where xid=${x.id}"
processor="CachedSqlEntityProcessor">
</entity>
<entity>
the Entity Processor always return the result from the fist query even though
the parameter is changed, It is happening because,
EntityProcessorBase.getNext() method doesn't reset the query and rowIterator
after calling DIHCacheSupport.getCacheData() method.
This can be fixed by changing the else block in getNext() method of
EntityProcessorBase from
else {
return cacheSupport.getCacheData(context, query, rowIterator);
}
to the code mentioned below:
else {
Map<String,Object> cacheData = cacheSupport.getCacheData(context, query,
rowIterator);
query = null;
rowIterator = null;
return cacheData;
}
