livy start error

[#1]

I was running livy fine before. After a recent merge from the main branch, I am seeing the following error starting livy even i am running it the same way as before. Does this mean a JDK version problem?

Exception in thread "main" java.lang.NoClassDefFoundError: java/lang/ProcessBuilder$Redirect
        at com.cloudera.hue.livy.server.Main$.sparkSubmitVersion(Main.scala:130)

This seems to be related to the maven version I used. Not a livy problem.
