Issue while running helloworld example on ubuntu 14.04

[palaiya]

I am getting the following error from here while running the HelloWorldServer.java on my local.
I am using openjdk version "1.8.0_91" on ubuntu 14.04.

Exception in thread "main" java.lang.NoSuchMethodError: com.google.common.base.Preconditions.checkArgument(ZLjava/lang/String;Ljava/lang/Object;Ljava/lang/Object;)V

The guava version is too old. You need to use at least version 20. We have discussed releasing another v1.1.x version that relaxes the Guava dependency back to where it was in v1.0.x, but today it isn't available.

Note that if you are using Spark, it will actually use the Guava version defined in your Spark.
Since Spark is using a relatively old Guava version 14.0.1 for Spark-2.1, you will need to go to your Spark jars folder and manually replace it
