Hi, > "chmod 655 <dir name>"
Shouldn't it be "755"? Otherwise the user is not allowed to list the content of the directory which will definitely cause an error. The user running Nutch is required to have "rwx" permissions in the "crawldb" folder and all its subfolders. > <http://lucene.472066.n3.nabble.com/file/t494657/nutch_error2.png> According to the error message in the screenshot, you first need to remove the file crawl/crawldb/.locked Injector: java.io.IOException: lock file crawl/crawldb/.locked already exists. at org.apache.nutch.util.LockUtil.createLockFile(LockUtil.java:51) at org.apache.nutch.util.LockUtil.createLockFile(LockUtil.java:81) at org.apache.nutch.crawl.CrawlDb.lock(CrawlDb.java:199) at org.apache.nutch.crawl.Injector.inject(Injector.java:400) at org.apache.nutch.crawl.Injector.run(Injector.java:570) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:70) at org.apache.nutch.crawl.Injector.main(Injector.java:535) Of course, this is probably because another error happened before. Could you delete the lock file, try again and share the logs of this run?
