Besides, you can write test cases for kylin's MR jobs with mrunit to debug, see org.apache.kylin.engine.mr.steps.NDCuboidMapperTest for reference.

In fact, it might be better adding more logs for tracing, in my opinion. If you do need to debug MR job directly, you may need to change your core-site.xml, mapred-site.xml and etc. to run MR job locally, It is theoretically possible, you can give a try :). you Zhuang <zhuangzixiao...@gmail.com> 于2018年10月30日周二 下午2:23写道： And also debug map reduce job ?

I can debug Kylin and standalone mr job in intellij idea with -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=9001 , but I don’t know how to debug both Kylin web server and whole build job flow, which mean idea can’t set up two remote debug servers 2. can we write a comprehensive documentation about full debug situations ? Because without debugging everything becomes awkward . -- Regards!Aron Tao
