我想做一个使用nutch1.9和solr4.10.2的网络爬虫的爬行工作，但当谈到索引有一个问题。我寻找这个问题，尝试了很多方法，但似乎都不管用。这就是我得到的：

Indexer: starting at 2015-03-13 20:51:08
Indexer: deleting gone documents: false
Indexer: URL filtering: false
Indexer: URL normalizing: false
Active IndexWriters :
  SOLRIndexWriter
solr.server.url : URL of the SOLR instance (mandatory)
solr.commit.size : buffer size when sending to SOLR (default 1000)
solr.mapping.file : name of the mapping file for fields (default solrindex-mapping.xml)
solr.auth : use authentication (default false)
solr.auth.username : use authentication (default false)
solr.auth : username for authentication
solr.auth.password : password for authentication

Indexer: java.io.IOException: Job failed!

at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:65)
at org.apache.nutch.indexer.IndexingJob.main(IndexingJob.java:186)

当我看到日志文件时，我得到的是：
