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.
Best,
Deepak
