Haofeng Tang updated DRILL-2468:
--------------------------------
Description:
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 an
embedded mode.
Thanks
