Nutch 2.2.1 + hBase

Question

Я пытаюсь запустить новую версию Apache Nutch для сканирования. Когда я запускаю скрипт /bin/crawl, он терпит неудачу и hadoop.log говорит:

java.lang.Exception: java.lang.NoSuchMethodError: org.apache.gora.persistency.Persistent.getSchema()Lorg/apache/avro/Schema; at org.apache.hadoop.mapred.LocalJobRunner $ Job.run (LocalJobRunner.java:354) Причина: java.lang.NoSuchMethodError: org.apache.gora.persistency.Persistent.getSchema()Lorg/apache/avro/Schema; в org.apache.gora.hbase.store.HBaseStore.put(HBaseStore.java:177)

Вот журнал:

Должен ли я установить некоторые артефакты Гора в ivy.xml или что-то? Пожалуйста, помогите мне.

Решаемые. Вы должны добавить правильную версию gora-hbase в свои библиотеки. Гур-HBase-0.3.jar
