[jira] [Comment Edited] (DRILL-4561) Rationalize jar structure to minimize client dependencies

["Paul Rogers (JIRA)" <ji...@apache.org>]

-------------------------------------------------------------

Good call. Indeed, mvn dependency:tree -Dverbose shows 

Curator uses Guava 16.0.1,
Calcite uses 14.0.1, 
Reflections uses 11.0.2, 
Codahale Metrics uses 18.0, as does Drill

I'm attempting to use the ZK cluster controller directly in my code so I may have class loader issues. I'll investigate more.

> In building the YARN Application Master (AM), we have need to include the bit of code that tracks Drill-bit registrations in ZK. Doing so needs at least two Drill Jars:
> org.apache.drill.exec/drill-java-exec
> org.apache.drill/drill-protocol
> Even with these, a Maven project fails to include some dependencies, resulting in missing classes:
> Exception in thread "main" java.lang.NoSuchMethodError: com.google.common.base.Stopwatch.createStarted()
> Two suggestions:
> 1. Adjust jars so that client code (such as to read ZK) is in a single jar.
> 2. Ensure Maven dependencies pull in required additional jars.
