I assume the issue was resolved after the version of Jackson was changed?
Please refer https://issues.apache.org/jira/browse/YARN-2092 and SAMZA-878
for more context.
Hadoop uses the following 4 jackson libs.
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-mapper-asl</artifactId>
<version>1.9.13</version>
</dependency>
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-core-asl</artifactId>
<version>1.9.13</version>
</dependency>
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-jaxrs</artifactId>
<version>1.9.13</version>
</dependency>
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-xc</artifactId>
<version>1.9.13</version>
</dependency>
As long as you have all these to 1.9.13, you should be all set.
Thanks,
