Jackson Dependency Not Declared in Hadoop POM
---------------------------------------------

Key: HADOOP-7461
URL: https://issues.apache.org/jira/browse/HADOOP-7461
Project: Hadoop Common
Issue Type: Bug
Components: build
Affects Versions: 0.20.2
Reporter: Ron Bodkin
Priority: Minor


This issue was identified and the fix & workaround was documented at

https://issues.cloudera.org/browse/DISTRO-44

The issue affects use of Hadoop 0.20.203.0 from the Maven central repo. I built a job using that maven repo and ran it, resulting in this failure:

Exception in thread "main" java.lang.NoClassDefFoundError: org/codehaus/jackson/map/JsonMappingException
at thinkbig.hadoop.inputformat.TestXmlInputFormat.run(TestXmlInputFormat.java:18)
at thinkbig.hadoop.inputformat.TestXmlInputFormat.main(TestXmlInputFormat.java:23)
Caused by: java.lang.ClassNotFoundException: org.codehaus.jackson.map.JsonMappingException

    (COMMENT: This bug still affects 0.20.205.0, four months after the bug was filed. This causes total failure, and the fix is trivial for whoever manages the POM -- just add the missing dependency! --ben)
