OK so I undertook the exercise of seeing what can/could possibly be upgraded by doing searches on Maven Central. The following outcomes can be interpreted as
artifact id: current version: latest version
cassandra-thrift:ditto (by the way do we require this if we are shifting to Hector client???)
commons-logging:1.1.1: at newest, however I don't see this actually being used anywhere can someone clarify why this is present.
libthrift:0.5.0:0.7.0 however same comment as above
As we all know hadoop can stay at 0.20.2 for the foreseeable future. The concern I have is with compatibility! This is an area I do not have much experience and I'm trying to get used to it. Once this is done the ant/ivy can follow suit fine, I don't have a problem with that.
Further to this, as explained above, I have not looked for any plugins for the pom.xml or anything similar
