I am using CDH 5.7 and porting few C UDF written for DB2 to Impala in C++, I have written lots of code based on the documentation, but when testing I am not getting desired output. I was finding out the ways to put DEBUG and logging statements during the functions calls, can somebody help me how to do that. I also need to know where they will be getting logged?
I am running my queries from impala-shell.
