@merrimanr Today I decided to run through the documentation to see how it works out. When trying to run the spring boot app through the `start.sh` script using an h2 database I got the error below. I did had h2 to my classpath instead of mysql.
I did some investigating and it seems like this is an issue with having multiple versions of guava. I used the following code to print which dependency guava is coming from.
```
System.out.println(FluentIterable.class.getProtectionDomain().getCodeSource().getLocation().toExternalForm());
```
It prints out the line below. It looks like it is getting the dependency from metron-statistics which uses version `12.0`. I believe spring needs `16.01`.
`
jar:file:/home/choosetwo/workspace/incubator-metron/metron-interface/metron-rest/target/lib/metron-rest-0.3.0.jar!/BOOT-INF/lib/metron-statistics-0.3.0.jar!/
`
After manually adding guava version `16.01` to the end of the classpath in `start.sh` the error below goes away, and everything works just fine. I think we may need to clean up the dependencies in `metron-rest`'s pom file.
