Re: Error Executing Command - Hadoop Bundle in Karaf
I had the problem of an older Xerces (2.9.1) bundle installed in Karaf. I stopped that Xerces bundle and all still *appeared* to work in Karaf. I figured there were no specific dependencies on that version (This may come back to bite me in the butt in the future). Despite stopping this bundle, I still encountered the org.apache.xerces.parsers.XIncludeAwareParserConfiguration error. I then removed the Xerces dependency within the Hadoop-Karaf 3.0.0-SNAPSHOT bundle. ( I also had to export org.apache.hadoop.fs and org.apache.hadoop.conf in order for the bundle dependent on Hadoop-Karaf 3.0.0-SNAPSHOT to work) I then installed the new Hadoop-Karaf Arenee version along with a separate Xerces 2.11.0 bundle. I no longer get the Xerces error. I do get a connection refused error but that's a different issue.

Error Executing Command - Hadoop Bundle in Karaf
Hi all, I've installed the Hadoop 3.0.0 SNAPSHOT from the blog. When trying to access an HDFS directly in Karaf, I receive the following error: karaf@rootla|grep -i hadoop [ 471] [Active ] [Created ] [ ] [ 80] Apache Hadoop Karaf (3.0.0.SNAPSHOT) karaf@roothadoop:fs -ls / Error executing command: org.apache.xerces.parsers.XIncludeAwareParserConfiguration cannot be cast to org.apache.xerces.xni.parser.XMLParserConfiguration Any suggestions for fixing this error?

Hi, remove the xercesImpl.jar from lib/endorsed, it should help. Regards JB On 05/22/2014 07:50 PM, arenee wrote: Hi all, I've installed the Hadoop 3.0.0 SNAPSHOT from the blog.

Re: Error Executing Command - Hadoop Bundle in Karaf
Thanks for the quick response. However, I don't seem to have the xercesImpl.jar in my $KARAF_HOME/lib/endorsed directory. I did a search for xercesImpl*.jar and only found it associated with the Hadoop-karaf bundle in $KARAF_HOME/data/cache/bundle471/version0.1/bundle.jar-embedded/xercesImpl-2.11.0.jar Any other suggestions? -- View this message in context: http://karaf.922171.n3.nabble.com/Error-Executing-Command-Hadoop-Bundle-in-Karaf-tp4033244p4033247.html Sent from the Karaf - Dev mailing list archive at Nabble.com.

Re: Error Executing Command - Hadoop Bundle in Karaf
By the way, I should probably update my bundle for Karaf 3.0.0 (if it's the version that you use) ;) Regards JB On 05/22/2014 08:09 PM, arenee wrote: Thanks for the quick response.

Re: Error Executing Command - Hadoop Bundle in Karaf
Hi, That's the problem. You shouldn't embed xercesImpl-2.11.0.jar in Hadoop-karaf bundle, you should use the one from container(with correct Import-Package). The error org.apache.xerces.parsers.XIncludeAwareParserConfiguration cannot be cast to org.apache.xerces.xni.parser.XMLParserConfiguration generally means same class loaded by different classloaders. embed jar usually is the culprit here. － Freeman(Yue) Fang Red Hat, Inc.
