Hi, I'm more than happy to share the little that is there (I will publish it on github and send link tomorrow).
I ended up copying my UDF (singl-file.java) into the simple-drill-function project where it got picked up. Then I discovered a whole new set of dependencies/limitations - The UDF are recompiled - any imports are invalid or at least overwritten - import org.joda.time.Period; (means that Period class is not resolved on runtime) - Error: SYSTEM ERROR: CompileException: Line 71, Column 26: Cannot determine simple type name "Period" - Calling any "outside" functions, like I was calling a static function of the new class (same file), leads to an errors as they are not not resolved - Error: SYSTEM ERROR: CompileException: Line 70, Column 35: A method named "roundTimeStamp" is not declared in any enclosing class nor any supertype, nor through a static import Perhaps this was mentioned in the documentation but this is, at the very least, not straight forward and super-inviting. Thank you for your assistance, we will keep trying :) Regards, -Stefan On Sun, Jul 19, 2015 at 11:34 PM, Tugdual Grall <[email protected]> wrote: > Hi Stefan, > > Do you think you can share your complete project ? > > This will help to debug it for you. > > T > > On Sunday, July 19, 2015, Stefán Baxter <[email protected]> wrote: > > > Hi Ted, > > > > I fetched this, built it and deployed it without problems. > > I can not see any real difference other than this deploys two .jar (I > tried > > that as well earlier). > > > > I'm still trying to figure out why Drill is not picking up my UDFs > > > > Regards, > > -Stefán > > > > On Sun, Jul 19, 2015 at 10:45 PM, Ted Dunning <[email protected] > > <javascript:;>> wrote: > > > > > Stefan, > > > > > > Have you seen this github project: > > > > > > https://github.com/mapr-demos/simple-drill-functions > > > > > > ? > > > > > > > > > On Sun, Jul 19, 2015 at 2:14 PM, Stefán Baxter < > > [email protected] <javascript:;>> > > > wrote: > > > > > > > Hi Jim, > > > > > > > > I'm still not able to make this work.
