What version of Avro are you using? You may want to try Avro 1.6.3 + Jackson 1.8.8.
This is related, but is not your exact problem. https://issues.apache.org/jira/browse/AVRO-1037 You are likely pulling in some other version of jackson somehow. You may want to use 'mvn dependency:tree' on your project to see where all the dependencies are coming from. That may help identify the culprit. -Scott On 3/19/12 5:06 PM, "Deepak Nettem" <deepaknet...@gmail.com> wrote: >Sorry, > >I meant, I added the jackson-core-asl dependency, and still get the error. > > <groupId>org.codehaus.jackson</groupId> > <artifactId>jackson-core-asl</artifactId> > <version>1.5.2</version> > <scope>compile</scope> > </dependency> > > >On Mon, Mar 19, 2012 at 8:05 PM, Deepak Nettem <deepaknet...@gmail.com> >wrote: > >Hi Tatu, > >I added the dependency: > ><dependency> > <groupId>org.codehaus.jackson</groupId> > <artifactId>jackson-mapper-asl</artifactId> > <version>1.5.2</version> > <scope>compile</scope> > </dependency> > > >But that still gives me this error: > >Error: >org.codehaus.jackson.JsonFactory.enable(Lorg/codehaus/jackson/JsonParser$F >eature;)Lorg/codehaus/jackson/JsonFactory; > >Any other ideas? > > >On Mon, Mar 19, 2012 at 7:27 PM, Tatu Saloranta <tsalora...@gmail.com> >wrote: > >On Mon, Mar 19, 2012 at 4:20 PM, Deepak Nettem <deepaknet...@gmail.com> >wrote: >> I found that the Hadoop lib directory contains >>jackson-core-asl-1.0.1.jar >> and jackson-mapper-asl-1.0.1.jar. >> >> I removed these, but got this error: >> hadoop Exception in thread "main" java.lang.NoClassDefFoundError: >> org/codehaus/jackson/map/JsonMappingException >> >> I am using Maven as a build tool, and my pom.xml has this dependency: >> >> <dependency> >> <groupId>org.codehaus.jackson</groupId> >> <artifactId>jackson-mapper-asl</artifactId> >> <version>1.5.2</version> >> <scope>compile</scope> >> </dependency> >> >> Any help would on this issue would be greatly appreciated. > > >You may want to add similar entry for jackson-core-asl -- mapper does >require core, and although there is transient dependency from mapper, >Maven does not necessarily enforce correct version. >So it is best to add explicit dependency so that version of core is >also 1.5.x; you may otherwise just get 1.0.1 of that one. > >-+ Tatu +- > > > > > > > >
