I was surprised to see the guava-11.0.2.jar in the /usr/lib/hadoop/lib directory of the HDP 1.3 sandbox VM. Some of my MapReduce jobs use a newer version of guava, and it seems like they are now picking up this older version instead (causing problems).
guava is not in my vanilla Apache Hadoop 1.2.1 install. is this an HDP-specific dependency, and is it expected to pre-empt client submitted jars in the classloaders for a MR job?
