It looks like Java 8 is more sensitive about classes from different JARs in the
same package. Removing servlet-api 2.5 allows the 3.0 servlet JAR to work
properly.
Since servlet-api 2.5 is coming from YARN, and we're only using YARN's AM
client libs (not the RM, NM, history server UI, etc), we should be safe here.
