I configured Nutch 2.1 with gora and mySql. Everything worked until I changed gora-sql-mapping.xml to add new field. I get these exceptions: Exception in thread "main" org.apache.gora.util.GoraException: java.io.IOException: java.lang.NullPointerException at org.apache.gora.store.DataStoreFactory.createDataStore(DataStoreFactory.java:167) at org.apache.gora.store.DataStoreFactory.createDataStore(DataStoreFactory.java:135) at org.apache.nutch.storage.StorageUtils.createWebStore(StorageUtils.java:75) at org.apache.nutch.crawl.InjectorJob.run(InjectorJob.java:214) at org.apache.nutch.crawl.Crawler.runTool(Crawler.java:68) at org.apache.nutch.crawl.Crawler.run(Crawler.java:136) at org.apache.nutch.crawl.Crawler.run(Crawler.java:250) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:65) at org.apache.nutch.crawl.Crawler.main(Crawler.java:257) Caused by: java.io.IOException: java.lang.NullPointerException at org.apache.gora.sql.store.SqlStore.readMapping(SqlStore.java:878) at org.apache.gora.sql.store.SqlStore.initialize(SqlStore.java:163) at org.apache.gora.store.DataStoreFactory.initializeDataStore(DataStoreFactory.java:102) at org.apache.gora.store.DataStoreFactory.createDataStore(DataStoreFactory.java:161) ... 8 more Caused by: java.lang.NullPointerException at org.apache.gora.sql.store.SqlStore.addField(SqlStore.java:828) at org.apache.gora.sql.store.SqlStore.readMapping(SqlStore.java:868) ... 11 more
