Subject Re: DIH throws NullPointerException when using dataimporter.functions.escapeSql with parent entities
Date Sat, 20 Oct 2012 03:18:50 GMT
If it worked before and does not work now, I don't think you are doing anything wrong :)

Do you have a different version of your JDBC driver?
Can you make a unit test with a minimal DIH script and schema?
Or, scan through all of the JIRA issues against the DIH from your old Solr capture date.

with parent entities
| 
| Hi folks,
| 
| I am currently migrating our Solr servers from a 4.0.0 nightly build
| (aprox. November 2011, which worked very well) to the newly released
| 4.0.0 and am running into some issues concerning the existing
| DataImportHandler configuratiions. Maybe you have an idea where I am
| going wrong here.
| 
| The following lines are a highly simplified excerpt from one of the
| problematic imports:
| 
| <entity name="path" rootEntity="false" query="SELECT p.id, IF(p.name
| IS NULL, '', p.name) AS name FROM path p GROUP BY p.id">
| 
|         <entity name="item" rootEntity="true" query="
|                         SELECT
|                                 i.*,
| 
| CONVERT('${dataimporter.functions.escapeSql(path.name)}' USING
| utf8) AS path_name
|                         FROM items i
|                         WHERE i.path_id = ${path.id}" />
| 
| </entity>
| 
| While this configuration worked without any problem for over half a
| year now, when upgrading to 4.0.0-BETA AND 4.0.0 the Import throws
| the
| followeing Stacktrace and exits:
| 
|  SEVERE: Exception while processing: path document :
| null:org.apache.solr.handler.dataimport.DataImportHandlerException:
| java.lang.NullPointerException
| 
| which is caused by
| 
| Caused by: java.lang.NullPointerException
|         at
|         org.apache.solr.handler.dataimport.EvaluatorBag$1.evaluate(EvaluatorBag.java:79)
| 
| In other words: The EvaluatorBag doesn't seem to resolve the given
| path.name variable properly and returns null.
| 
| Does anyone have any idea?
| Appreciate your input!
| 
| Regards
| Dom
