Subject [jira] [Commented] (DRILL-4561) Rationalize jar structure to minimize client dependencies
Date Wed, 30 Mar 2016 20:04:25 GMT

    [ https://issues.apache.org/jira/browse/DRILL-4561?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15218726#comment-15218726

Laurent Goujon commented on DRILL-4561:

It didn't throw ClassNotFoundException so I guess the class is present in the classpath. Isn't
that simply a conflict between guava version used by drill, and guava version used by Hadoop?

>                 Key: DRILL-4561
>                 URL: https://issues.apache.org/jira/browse/DRILL-4561
>             Project: Apache Drill
>          Issue Type: Improvement
>          Components:  Server
>            Reporter: Paul Rogers
>            Priority: Minor
> 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
> 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.
