Use bootstrap to replace default jar on EMR

I am on a EMR cluster with AMI 3.0.4. Once the cluster is up, I ssh to master and did the following manually:

---

cd /home/hadoop/share/hadoop/common/lib/

rm guava-11.0.2.jar

wget http://ift.tt/1yB8Lhz

chmod 777 guava-14.0.1.jar

---

Is it possible to do above in a bootstrap action? Thanks!
