> Key: DRILL-2468
> URL: https://issues.apache.org/jira/browse/DRILL-2468
> Project: Apache Drill
> Issue Type: Bug
> Components: Execution - Codegen, Execution - Relational Operators
> Affects Versions: 0.7.0, 0.8.0
> Environment: CentOS 64-bit
> Reporter: Haofeng Tang
> Assignee: Sudheesh Katkam
> Fix For: 0.9.0
>
>
> I followed these articles to create a custom function. I was able to repeat
> these examples to build, and run queries using these new functions
> successfully. But if I used some 3rd party libraries in my code, of cause
> with all dependencies resolved with maven, I received errors -- although I
> was able to build and run drill, I received an error "No applicable
> constructor/method found for actual parameters "java.lang.Object";"
> when I tried to use the added function in my query. Seems to be a classloader
> issue.
> All my test is done on a local CentOS node, and drill was deployed in
> embedded mode.
> Thanks
