Hi, I just cloned Nutch github repo and checked out 2.x branch. I compiled that with ant clean and ant runtime. Everything worked great.
But when i tried to inject some URL it say's the following error. $ $NUTCH_ROOT/runtime/local/bin/nutch inject /seed InjectorJob: starting at 2016-12-11 19:35:00 InjectorJob: Injecting urlDir: /seed InjectorJob: org.apache.gora.util.GoraException: java.lang.RuntimeException: 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:78) at org.apache.nutch.crawl.InjectorJob.run(InjectorJob.java:234) at org.apache.nutch.crawl.InjectorJob.inject(InjectorJob.java:268) at org.apache.nutch.crawl.InjectorJob.run(InjectorJob.java:291) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:70) at org.apache.nutch.crawl.InjectorJob.main(InjectorJob.java:300) Caused by: java.lang.RuntimeException: java.io.IOException: java.lang.NullPointerException at org.apache.gora.mongodb.store.MongoStore.initialize(MongoStore.java:131) at org.apache.gora.store.DataStoreFactory.initializeDataStore( DataStoreFactory.java:102) at org.apache.gora.store.DataStoreFactory.createDataStore( DataStoreFactory.java:161) ... 7 more Caused by: java.io.IOException: java.lang.NullPointerException at org.apache.gora.mongodb.store.MongoMappingBuilder.fromFile( MongoMappingBuilder.java:123) at org.apache.gora.mongodb.store.MongoStore.initialize(MongoStore.java:118) ... 9 more Caused by: java.lang.NullPointerException at org.apache.gora.mongodb.store.MongoMapping.newDocumentField( MongoMapping.java:109) at org.apache.gora.mongodb.store.MongoMapping.addClassField( MongoMapping.java:169) at org.apache.gora.mongodb.store.MongoMappingBuilder.loadPersistentClass( MongoMappingBuilder.java:169) at org.apache.gora.mongodb.store.MongoMappingBuilder.fromFile( MongoMappingBuilder.java:112) ... 10 more I have my gora.properties file OK like following gora.datastore.autocreateschema=true gora.datastore.default=org.apache.gora.mongodb.store.MongoStore gora.mongodb.override_hadoop_configuration=false gora.mongodb.mapping.file=/gora-mongodb-mapping.xml gora.mongodb.servers=localhost:27017 gora.mongodb.db=tempnutch gora.mongodb.login=test gora.mongodb.secret=test gora.mongodb.readpreference=primary gora.mongodb.writeconcern=acknowledged my mongodb is working well. I tested that. I am using Mongodb 3.0 version. And also in ivy/ivy.xml i uncommented mongodb gora dependencies. So it's any known issue or anything I can workout with any advise? Thanks, Shaharia
