If I exclude the dependency from the required library it will fail to work.  I was wondering if anyone had any experience with using a later version of HttpClient with Storm since it is present in the /lib folder that storm uses.  I plan to just drop the later version in and see if it works but I was hoping someone would have some experience with this and any issues I may run into.

We had the same problem and excluded storms version in favor of the 4.3 version. Storm has been working just fine since. Granted this is currently only in our dev/qa env.

Thanks Nick.  I'll go ahead and give that a whirl.

The only thing I can think of that might crop up is that the classpath builder in the storm launcher might try to put the storm version, in lib folder, in front of your uber jar. So a solution might be to just swap that version as well.

But let me know how it goes. We haven't full tested trying this on our own.

We sucessfully replaced the http*.jar in the lib folder of storm by a new version without any problems.

You might do that with all the storm installation on the cluster.

Question also becomes is the http dependency only used for the WebUI or used through out. If just the WebUI will the splitting of the code base up maybe help resolve this issue in the future, or should a bug report be filed to update this for a future release?
