Hello guys, I'm trying to use Nutch 2.0 release in a standalone node for testing (no Hadoop for now) and using a MySQL as a storage backend. As I have no experience with HBase, I decided to use MySQL for now to understand what each command does, as those have changed from the 1.X branch. I've followed the nutch2 tutorial and the gora documentation for configuring the installation. I can Inject, generate and fetch, but when I use the host commands (hostinject,updatehostdb and readhostdb) I get the same NULL pointer exception:
HostInjectorJob: org.apache.gora.util.GoraException: 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:69) at org.apache.nutch.host.HostInjectorJob.inject(HostInjectorJob.java:146) at org.apache.nutch.host.HostInjectorJob.run(HostInjectorJob.java:160) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:65) at org.apache.nutch.host.HostInjectorJob.main(HostInjectorJob.java:174) Caused by: java.lang.NullPointerException at org.apache.gora.sql.store.SqlStore.addColumn(SqlStore.java:790) at org.apache.gora.sql.store.SqlStore.createSqlTable(SqlStore.java:802) at org.apache.gora.sql.store.SqlStore.initialize(SqlStore.java:165) at org.apache.gora.store.DataStoreFactory.initializeDataStore(DataStoreFactory.java:102) at org.apache.gora.store.DataStoreFactory.createDataStore(DataStoreFactory.java:161) ... 6 more The only modification I did to the schema was making the 'text' field bigger, from 32000 VARCHARs to 60000, as I was getting errors when using the parsing tool. Any tips/ideas/pointers? Thanks for your time, Joan
