Project: Nutch
Issue Type: Bug
Affects Versions: 1.4
Environment: Ubuntu 10.04
Reporter: Dennis Spathis
Assignee: Lewis John McGibbney
Fix For: 2.3, 1.8
Attachments: NUTCH-1253-2.x-v2.patch, NUTCH-1253-nutchgora.patch,

The Nutch 1.4 distribution includes
- nekohtml-0.9.5.jar (under .../runtime/local/plugins/lib-
nekohtml)
- xercesImpl-2.9.1.jar (under .../runtime/local/lib)
These two JARs appear to be incompatible versions. When the HtmlParser
(configured to use neko) is invoked during a local-mode crawl, the parse
fails due to an AbstractMethodError. (Note: To see the AbstractMethodError,
rebuild the HtmlParser plugin and add a
catch(Throwable) clause in the getParse method to log the stacktrace.)
I found that substituting a later, compatible version of nekohtml (1.9.11)
fixes the problem.
Curiously, and in support of the above, the nekohtml plugin.xml file in
Nutch 1.4 contains the following:
plugin
id=lib-nekohtml
name=CyberNeko HTML Parser
version=1.9.11
provider-name=org.cyberneko
runtime
library name=nekohtml-0.9.5.jar
export name=*/
/library
/runtime
/plugin
Note the conflicting version numbers (version tag is 1.9.11 but the
specified library is nekohtml-0.9.5.jar).
Was the 0.9.5 version included by mistake? Was the intention rather to
include 1.9.11?

Tomasz Struczynski commented on NUTCH-1253:

I don't have time for much analysis, but, the cause is probably this feature:
{noformat}
parser.setFeature(http://cyberneko.org/html/features/report-errors;,
LOG.isTraceEnabled());
{noformat}
as this is the only place which uses trace setting and is not surrounded by
try... catch.
Anyway, the problem is still unresolved (using gora branch).
Incompatible neko and xerces versions
-
Key: NUTCH-1253
URL: https://issues.apache.org/jira/browse/NUTCH-1253
Project: Nutch
Issue Type: Bug
Affects Versions: 1.4
Environment: Ubuntu 10.04
Reporter: Dennis Spathis
Attachments: NUTCH-1253-nutchgora.patch, NUTCH-1253.patch
The Nutch 1.4 distribution includes
- nekohtml-0.9.5.jar (under .../runtime/local/plugins/lib-
nekohtml)
- xercesImpl-2.9.1.jar (under .../runtime/local/lib)
These two JARs appear to be incompatible versions. When the HtmlParser
(configured to use neko) is invoked during a local-mode crawl, the parse
fails due to an AbstractMethodError. (Note: To see the AbstractMethodError,
rebuild the HtmlParser plugin and add a
catch(Throwable) clause in the getParse method to log the stacktrace.)
I found that substituting a later, compatible version of nekohtml (1.9.11)
fixes the problem.
Curiously, and in support of the above, the nekohtml plugin.xml file in
Nutch 1.4 contains the following:
plugin
id=lib-nekohtml
name=CyberNeko HTML Parser
version=1.9.11
provider-name=org.cyberneko
runtime
library name=nekohtml-0.9.5.jar
export name=*/
/library
/runtime
/plugin
Note the conflicting version numbers (version tag is 1.9.11 but the
specified library is nekohtml-0.9.5.jar).
Was the 0.9.5 version included by mistake? Was the intention rather to
include 1.9.11?

I just found out that the exception is CAUSED BY enabling trace logging. That is why it is so confusing. My previous statement about it not affecting nutchgora is not true it seems. It indeed affects both trunk and nutchgora. See the following instructions for reproducing the problem: ferdy@ftm:~/workspace/nutchtrunk/runtime/local$ bin/nutch parsechecker http://www.iana.org/; ... Version: 5 Status: success(1,0) ... Now what happens when I add the following line to log4j.properties. (Note that the comment by Dennis has a type in this line). log4j.logger.org.apache.nutch.parse.html=TRACE,cmdstdout ferdy@ftm:~/workspace/nutchtrunk/runtime/local$ bin/nutch parsechecker http://www.iana.org/; ... Version: 5 Status: failed(2,200): org.apache.nutch.parse.ParseException: Unable to successfully parse content ... So this is very obscure. It might be a trace logging statement that triggers the exception. It cannot be something else.

When running it with default options in local mode, every parse simply fails. This is pretty suprising. With the help of Dennis' instructions it indeed becomes more clear what the error is about. Note that nutchgora is not affected. Though at first sight they seem to be using the same library versions. I'm amazed that this error has not been noticed earlier. I cannot speak for users/devs that are on 1.x, so I kindly ask if one of them is able to pick this issue up. (Or least provide some insight). My guess is that they either use tagsoup (instead of neko) or parse-tika for html parsing. Then again if that's the case I don't know why the defaults are now the way they are. Because of this I have not yet tested any of your patches, sorry Lewis.

The fact that they bothered to change this version number in the first place is pretty curious in itself, because most plugins simply remain at version 1.0 despite several changes. Not that it matters, but just to indicate that this number has no real purpose. As to nekohtml jar, am not sure why it's still at this specific version, or why it is the preferred setting. Digging up the issues or mailing lists might give you some more info about this. It might be worth looking into tagsoup. I do find your AbstractMethodError curious though. Are you sure it's because of nekohtml and xerces? Can you provide a stracktrace?
