Chao Long commented on KYLIN-3731:
----------------------------------
Sorry, I don't understand what's your meaning. If you use hive view, you may
convert array to string in the view, then Kylin will load string type data not
array type data, right?
If you provide query sql, maybe I can understand well.
> java.lang.IllegalArgumentException: Unsupported data type array<string> at

> As kylin was recently upgraded from 2.3 to 2.5.1, its data type of array
> metadata was found to be unsupported and the following exception occurred
> "java. lang. IllegalArgumentException: Unsupported data type array", are in
> kylin2.3 hive data storage array before running this type is no problem,
> there is the lead in building a cube when the third step is as follows
> "org. apache. kylin. engine. mr. Exception. MapReduceException: no counters
> for the job", could you tell me how to solve the problem without changing
> data structure situation now? please look up attachment.
