 Hello,> "chmod "

Shouldn’t it be “755”? Otherwise, the user has the right to useDirectory content that is bound to result in an error.The user running Nutch is prompted to enter “rwx” in the permissions inthe “crawldb” directory and all its subfolders.> According to the error message in the screenshot, you need to delete firstfile crawl / crawldb / .lockedInjector: java.io.IOException: Safe scan for files / crawldb / .locked already exists. at org.apache.nutch.util.LockUtil.createLockFile (LockUtil.java:51) during 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) only with org.apache.nutch.crawl.Injector.run (Injector.java:570) by visiting org.apache.hadoop.util.ToolRunner.run (ToolRunner.java:70). at org.apache.nutch.crawl.Injector.main (Injector.java:535)Of course, this is probably due to the fact that there was another error earlier.Can people Remove, lock file, try again, share logs fromthis course?Many thanks,Sebastian02/20/19 20:40 cesium wrote:> I am getting big error when I try to use nutch to run your current command ./nutch> enter urls crawldir / crawldb.

Java.io.IOException: No table of contents specified in: NutchConf: nutch-default.xml. … mapred-default.xml

The explorer tool expects the folder where the filename is located with the bootstrap web addresses as an initial parameter. For example, if your urls.txt is in / nutch / seed, the command will look like this: start scanning – dir / user / nutchuser …

Exception: java.net.Invalid socketException: Argument, or it cannot assign the requested address in Fedora Core 3 or 4

To solve this problem, add the following Java parameter to instantiate cappuccino in bin / nutch:

# run “$ JAVA” professionally $ JAVA_HEAP_MAX $ NUTCH_OPTS $ JAVA_IPV4 -classpath “$ CLASSPATH” $ CLASS “$ @”

FileNotFoundException: 1

Delay 1 fails scan validation and subdirectories are created as well; Ant also doesn’t compile problems; ROOT.war is installed and running; The address file exists. Adding ./ or a full course like the x below doesn’t change anything.The server has Squid installed at 80 and the actual Apache 1.3 at 81. Catalina is at 8080 and is therefore ready to use.

This always results in an over-error, while missing a delay tag gives the impression that (smile) works … I’ve tried using the -delay tag in several places above, it always suffers fail

nutch 0.7 Apache Tomcat / 5.0.19 jdsk 1.4.2-b28 Sun Microsystems Inc. Linux (Suse 8.2 1.5 years, but updated) Linux Kernel 2.4.21 i386

The

tag works without delay, but I can’t share it with other sites right away. What am I wrong? do

Why am I getting the error “123456 104934 Retrieve from http: //mydomain/index.html failed with: net.nutch.net.protocols.http.HttpError: HTTP Error: 401” in the case when the probe is running ?

An HTTP 401 error is returned from a remote web server if you are not certified to view the page. Nutch does not necessarily support HTTP authentication at this time, but it would certainly be trivial to add it after checking the pure HTTPClient fetch code.
