Настройка Nutch 2.3 с HSQL 2.3.3 — ClassNotFoundException: org/apache/avro/ipc/ByteBufferOutputStream

Я получаю ClassNotFoundException: org/apache/avro/ipc/ByteBufferOutputStream, когда я запускаю apache Nutch с HSQLDB, хотя у меня есть все jar-файлы, связанные с avro, в lib

    avro-1.7.6.jar
    avro-compiler-1.7.6.jar
    avro-ipc-1.7.6.jar
    avro-mapred-1.7.6.jar

Вот что я сделал:

1. HSQLDB запущен и работает

   root@elephant hsqldb#  sudo java -cp /home/hsqldb/hsqldb-2.3.3/hsqldb/lib/hsqldb.jar org.hsqldb.server.Server --props /home/hsqldb/hsqldb-2.3.3/hsqldb/conf/server.properties
   [Server@372f7a8d]: [Thread[main,5,main]]: checkRunning(false) entered
   [Server@372f7a8d]: [Thread[main,5,main]]: checkRunning(false) exited
   [Server@372f7a8d]: Startup sequence initiated from main() method
   [Server@372f7a8d]: Loaded properties from [/home/hsqldb/hsqldb-2.3.3/hsqldb/conf/server.properties]
   [Server@372f7a8d]: Initiating startup sequence...
   [Server@372f7a8d]: Server socket opened successfully in 28 ms.
   [Server@372f7a8d]: Database [index=0, id=0, db=file:/home/hsqldb/hsqldb-2.3.3/hsqldb/data/nutch, alias=nutchdb] opened sucessfully in 1406 ms.
   [Server@372f7a8d]: Startup sequence completed in 1438 ms.
   [Server@372f7a8d]: 2015-12-26 18:30:13.841 HSQLDB server 2.3.3 is online on port 9001
   [Server@372f7a8d]: To close normally, connect and execute SHUTDOWN SQL
   [Server@372f7a8d]: From command line, use [Ctrl]+[C] to abort abruptly
   

2. Настроенный ivy/ivy.xml

раскомментированы строки ниже в ivy.xml

 <dependency org="org.apache.gora" name="gora-core" rev="0.5" conf="*->default"/> 

и

<dependency org="org.apache.gora" name="gora-sql" rev="0.1.1-incubating"
   conf="*->default" />

раскомментировал следующие строки conf/gora.properites

###############################
# Default SqlStore properties #
###############################

gora.sqlstore.jdbc.driver=org.hsqldb.jdbc.JDBCDriver
gora.sqlstore.jdbc.url=jdbc:hsqldb:hsql://localhost/nutchdb
gora.sqlstore.jdbc.user=sa
gora.sqlstore.jdbc.password=

3. Запустил сборку муравья

   ant runtime
   

4. Добавлена ​​конфигурация для nutch-site.xml

   root@elephant conf# cat nutch-site.xml
   <?xml version="1.0"?>
   <?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
   
   <!-- Put site-specific property overrides in this file. -->
   
   <configuration>
   
           <property>
                   <name>storage.data.store.class</name>
                   <value>org.apache.gora.sql.store.SqlStore</value>
           </property>
   
           <property>
                   <name>http.agent.name</name>
                   <value>NutchCrawler</value>
           </property>
   
           <property>
                   <name>http.robots.agents</name>
                   <value>NutchCrawler,*</value>
           </property>
   
   </configuration>
   

5. Создан seed.txt в папке URL.

6. Выполнил nutch, введя URL-адреса
