Steve Loughran commented on HADOOP-13692:
-----------------------------------------
Looking at the spark stuff, I'm explicitly adding in (and blaming on aws SDK
10.6+), another jackson entry
{code}
<dependency>
<groupId>com.fasterxml.jackson.dataformat</groupId>
<artifactId>jackson-dataformat-cbor</artifactId>
<version>${fasterxml.jackson.version}</version>
</dependency>
{code}
Looking into HADOOP-13050; looks like it comes in after AWS SDK 10.6, so not
relevant.

> hadoop-aws should declare explicit dependency on Jackson 2 jars to prevent

> 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.
