Steffen Moelter created SOLR-3791: ------------------------------------- Summary: SortedMapBackedCache.java throws NullPointerException Key: SOLR-3791 URL: https://issues.apache.org/jira/browse/SOLR-3791 Project: Solr Issue Type: Bug Components: contrib - DataImportHandler Affects Versions: 3.6.1 Environment: Debian Reporter: Steffen Moelter
As datasource is a mysql via jdbc configured in the DIH. There are some sql statements in entities, that delivers NULL values in some fields. When this entities do have processor="CachedSqlEntityProcessor", a NullPointerException will be thrown. I Tried it on different machines, with different copies of the index. e.g.: <entity processor="CachedSqlEntityProcessor" name="locator_ids" query=" SELECT l1.id AS l1id, l2.id AS l2id, l3.id AS l3id, l4.id AS l4id, l5.id AS l5id, l6.id AS l6id, l7.id AS l7id FROM locators l1 LEFT JOIN locators l2 ON l1.parent_id = l2.id .... and so on delivers a result like: +-------+------+------+------+------+------+------+ | l1id | l2id | l3id | l4id | l5id | l6id | l7id | +-------+------+------+------+------+------+------+ | 21843 | 855 | 223 | 66 | 12 | 1 | NULL | +-------+------+------+------+------+------+------+ The SortedMapBackedCache throws the NullPointer. Staktrace: java.lang.NullPointerException at java.util.TreeMap.getEntry(TreeMap.java:341) at java.util.TreeMap.get(TreeMap.java:272) at org.apache.solr.handler.dataimport.SortedMapBackedCache.add(SortedMapBackedCache.java:57) at org.apache.solr.handler.dataimport.DIHCacheSupport.populateCache(DIHCacheSupport.java:124) at org.apache.solr.handler.dataimport.DIHCacheSupport.getSimpleCacheData(DIHCacheSupport.java:199) at org.apache.solr.handler.dataimport.DIHCacheSupport.getCacheData(DIHCacheSupport.java:147) at org.apache.solr.handler.dataimport.EntityProcessorBase.getNext(EntityProcessorBase.java:132) at org.apache.solr.handler.dataimport.SqlEntityProcessor.nextRow(SqlEntityProcessor.java:75) at org.apache.solr.handler.dataimport.EntityProcessorWrapper.pullRow(EntityProcessorWrapper.java:330) at org.apache.solr.handler.dataimport.EntityProcessorWrapper.nextRow(EntityProcessorWrapper.java:296) at org.apache.solr.handler.dataimport.DocBuilder.buildDocument(DocBuilder.java:683) I had to give an onError="continue" to the entity, in order to get the proper stacktrace. Leaving out the onError property (default=Abort) suppresses the stacktrace in EntityProcessorWrapper.java line 332 The DIH version 3.5.0 is not affected, works fine for me -- This message is automatically generated by JIRA.
