Hi, when trying to run the jar, I get the following error:

vagrant@precise32:~/recipes-rss$ java -jar rss-middletier/build/libs/rss-middletier-0.1.0-SNAPSHOT.jar

The wiki currently says:

After a successful build, you can find the following executable jars

RSS Middle Tier (./rss-core/build/libs/rss-core-.jar )
RSS Edge (./rss-edge/build/libs/rss-edge-.jar )

There should be 3 folders: rss-core, rss-middletier and rss-edge

https://github.com/Netflix/recipes-rss/wiki/Building-RSS-Middle-Tier-and-Edge

We are using recipes-rss in a research experiment. The setup is as follows:

• Edge node
• Middletier node
• Eureka node
• Cassandra node
• RSS feed server

Each node is a separate physical machine. The load is generated by JMeter where one user makes a request (add, remove feed) to the edge every 2 seconds.
At random points in time, the middletier encounters the following exceptions.

We assume that the problem might lie in netty. Could you confirm our assumption?
If this is the case, we plan to upgrade netty (including other frameworks) to the new version and see if it fixes the problem.

Hi,

the current master branch fails on the javadoc and FindBugs gradle tasks when building. If I comment them, everthing else builds just fine.

Moreover, after following the Running the RSS Reader Recipees application guide and having everthing up and running, the call to http://localhost:9090/jsp/rss.jsp (as indicated) fails with this stacktrace:

I think most other applications will need to specify

com.netflix.karyon.server.base.packages

To get governator working. I think you have been able to avoid this in the rss-recipes config as it defaults to com.netflix and your sample is in com.netflix.

Please note if this is incorrect and close or take this as suggestion that should be documented.

We should have a reference implementation of the 2.0 IPC stack (ribbon and karyon) in the recipes-rss project for people to better understand how IPC 2.0 works.

Since, there is value in having both 1.X and 2.X implementations. I will create a 2.x branch which we can later merge into master, moving the current master to 1.x branch.

On running clean build Checkstyle is not able to perform due to DoubleCheckedLocking being removed and it's specified in the configuration.

http://stackoverflow.com/questions/12795935/checkstyle-eclipse-plugin-doesnt-work

Is the LICENSE file meant to be 20MB? Seems to be a binary file. Is it missing a file extension?

When running the steps in the wiki to Build the project found (here)[https://github.com/Netflix/recipes-rss/wiki/Building-RSS-Middle-Tier-and-Edge], errors will occur. Switching to Java 7 successfully builds the project.
