Chris Nauroth created HADOOP-13692:
--------------------------------------
Summary: hadoop-aws should declare explicit dependency on Jackson
2 jars to prevent classpath conflicts.
Key: HADOOP-13692
URL: https://issues.apache.org/jira/browse/HADOOP-13692
Project: Hadoop Common
Issue Type: Sub-task
Components: fs/s3
Reporter: Chris Nauroth
Assignee: Chris Nauroth
Priority: Minor
If an end user's application has a dependency on hadoop-aws and no other Hadoop
artifacts, then it picks up a transitive dependency on Jackson 2.5.3 jars
through the AWS SDK. This can cause conflicts at deployment time, because
Hadoop has a dependency on version 2.2.3, and the 2 versions are not compatible
with one another. We can prevent this problem by changing hadoop-aws to
declare explicit dependencies on the Jackson artifacts, at the version Hadoop
wants.
