> 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
> Original Estimate: 1m
> Remaining Estimate: 1m
>
> When child entities are created and the child entity is provided with a parametrized query as below,
> {code:xml}
> <entity name="x" query="select * from x">
> <entity name="y" query="select * from y where xid=${x.id}" processor="CachedSqlEntityProcessor">
> </entity>
> <entity>
> {code}
> 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
> {code}
> else {
> return cacheSupport.getCacheData(context, query, rowIterator);
>
> }
> {code}
> to the code mentioned below:
> {code}
> else {
> Map<String,Object> cacheData = cacheSupport.getCacheData(context, query, rowIterator);
> query = null;
> rowIterator = null;
> return cacheData;
> }
> {code}
> Update: But then, the caching doesn't seem to be working...
