---------------------------------------------------------------
Hi, mainly hive data storage table is stored inside the fact table is a complex
data type is an array, and create a hive view, and kylin dimension table to
build inside have to field data cube, so an error directly, I read the class
source code should be under the lack of judgment logic, so lead to kylin third
step direct error when creating the cube.
kylin itself supports complex data types, and that logic aside, if kylin does
not support complex data types, hive data tables cannot be loaded and used in
kylin's web interface.
