Let's move this to dev@ list instead of JIRA if this is still an issue.
> Incompatibility with Hadoop/HBase cglib/asm dependencies
> --------------------------------------------------------
>
> Key: KNOX-943
> URL: https://issues.apache.org/jira/browse/KNOX-943
> Project: Apache Knox
> Issue Type: Bug
> Affects Versions: 0.12.0
> Reporter: Shane Kumpf
> Priority: Minor
>
> I maintain the
> [hadoop-mini-clusters|https://github.com/sakserv/hadoop-mini-clusters]
> project and have been working to update to the latest knox version in HDP
> 2.6.
> Unfortunately, I'm running into an issue with different cglib/asm dependency
> versions for the WebHDFS/Knox and Stargate/Knox tests that results in the
> following exception.

> I've attempted to exclude the various versions of asm/cglib, use cglib-nodep,
> relocate asm packages, etc. Any changes I make results in another system
> failing, i.e. excluding the older asm versions results in jersey failures.
> Here is a branch with the all of the updates that runs into the exception
> above. [https://github.com/sakserv/hadoop-mini-clusters/tree/hdp26]
> The specific test that fails is:
> [KnoxLocalClusterIntegrationTest|https://github.com/sakserv/hadoop-mini-clusters/blob/hdp26/hadoop-mini-clusters-knox/src/test/java/com/github/sakserv/minicluster/impl/KnoxLocalClusterIntegrationTest.java].
> The ASM FAQ talks about how tools and frameworks should repackage ASM, and it
> seems many already do. [http://asm.ow2.org/doc/faq.html#Q15]
> Any thoughts on how to address this?
