I was able to follow the custom function articles to create new functions. However, when I tried to create my own test custom functions, where some 3rd party libraries are needed, I wasn't able to get it to work. Here's my test:
-- Created class "MyClass" in drill-java-exec. Since there're string operations in this class depending on maven project-A (a 3rd party library), I added project-A in drill-java.exec dependency list; -- Built drill; -- Deployed the target apache-drill-0.8.0-SNAPSHOT.tar.gz; -- Launched drill, and ran query "select MyClass(string_column) from my_table" This gives me an error: >Query failed: Query stopped., Line 67, Column 58: No applicable constructor/method found for actual parameters "java.lang.Object"; candidates are: "public void com.thf.test.Segment.setStart(com.thf.test.Point)" [ 3deedeb2-42fa-4fa7-a8a7-4eb802451d58 on localhost:31010 ] >Error: exception while executing query: Failure while executing query. (state=,code=0) where, both com.thf.test.Segment and com.thf.test.Point are classes from project-A. Any idea of how to proceed? Suggestion would be appreciated. Regards
