Hi,
Your can read source code of class org.apache.kylin.tool.metrics.systemcube.SCCreator to learn its logic, the creation of create_hive_tables_for_system_cubes.sql is done by method generateAllSQL(). If no data found in your hive tables, please check the content of create_hive_tables_for_system_cubes.sql -- Best regards, Ni Chunen / George At 2019-04-09 16:13:29, "梁刚" <[email protected]> wrote: Hi All, I created the “system cube” according to http://kylin.apache.org/cn/docs/tutorial/setup_systemcube.html , but I found there was no data in hive tables of "kylin.hive_metrics_query_prod, kylin.hive_metrics_query_cube_prod, kylin.hive_metrics_job_prod". I want to know the data generation logic of these hive tables? or how to configure these logics? it seems there is no official reference documentation about this question。Please help!
